Part 13
PROPER TEMPERATURE OF THE OVEN.--The objects to be attained in the baking of bread are to break up the starch and gluten cells of the Sour so as to make them easily digestible, to destroy the yeast plant, and render permanent the cells formed by the action of the carbonic acid gas. To accomplish well these ends, the loaf must be surrounded by a temperature ranging from 400° to 600°. The oven should be one in which the heat is equal in all parts, and which can be kept at a steady, uniform heat. Old-fashioned brick ovens were superior in this respect to most modern ranges. The fire for baking bread should be of sufficient strength to keep the oven heated for at least an hour. If the oven has tendency to become too hot upon the bottom, a thin, open grate, broiler, or toasting rack, should be placed underneath the tins to allow a circulation of air and avoid danger of burning. If the heat be insufficient, fermentation will not cease until the bread has become sour; the cells will be imperfectly fixed or entirely collapsed; too little of the moisture will have evaporated, and the result will be a soft, wet, and pasty or sour loaf. If the heat be too great, the bread will be baked before it has perfectly risen, or a thick, burned crust will be produced, forming a non-conducting covering to the loaf, which will prevent the heat from permeating the interior, and thus the loaf will have an overdone exterior, but will be raw and doughy within. If, however, the temperature of the oven be just right, the loaf will continue for a little time to enlarge, owing to the expansion of the carbonic acid gas, the conversion of the water into steam, and the vaporizing of the alcohol, which rises in a gaseous form and is driven off by the heat; a nicely browned crust will be formed over the surface, the result of the rapid evaporation of water from the surface and consequent consolidation of the dough of this portion of the loaf, and a chemical change caused by the action of the heat upon the starch by which is converted into dextrine, finally assuming a brown color due to the production of a substance known to the chemist as _assama_.
Bread is often spoiled in the baking. The dough may be made of the best of flour and yeast, mixed and kneaded in the most perfect manner, and may have risen to the proper degree of lightness' before going to the oven, yet if the oven is either too hot or not hot enough, the bread will be of an inferior quality.
Without an oven thermometer, there is no accurate means of determining the temperature of the oven; but housekeepers resort to various means to form a judgment about it. The baker's old-fashioned method is to throw a handful of flour on the oven bottom. If it blackens without igniting, the heat is deemed sufficient. Since the object for which the heat is desired is to cook the flour, not to burn it, it might be supposed that this would indicate too high a temperature; but the flour within the loaf to be baked is combined with a certain amount of moisture, the evaporation of which lowers the temperature of the bread considerably below that of the surrounding heated atmosphere. The temperature of the inner portion of the loaf cannot exceed 212° so long as it continues moist. Bread might be perfectly cooked at this temperature by steam, but it would lack that most digestible portion of the loaf, the crust.
A common way of ascertaining if the heat of the oven is sufficient, is to hold the bare arm inside it for a few seconds. If the arm cannot be held within while thirty is counted, it is too hot to begin with. The following test is more accurate: For rolls, the oven should be hot enough to brown a teaspoonful of flour in _one_ minute, and for loaves in _five_ minutes.
The temperature should be high enough to arrest the fermentation, which it will do at a point considerably below the boiling point of water, and at the same time to form a shell or crust, which will so support the dough as to prevent it from sinking or collapsing when the evolution of carbonic acid gas shall cease; but it should not be hot enough to brown the crust within ten or fifteen minutes. The heat should increase for the first fifteen minutes, remain steady for the next fifteen minutes, and may then gradually decrease during the remainder of the baking. If by any mischance the oven be so hot as to brown the crust too soon, cover the loaf with a clean paper for a few minutes. Be careful that no draught reaches the bread while baking; open the oven door very seldom, and not at all for the first ten minutes. If it is necessary to turn the loaf, try to do so without bringing it to the air. From three fourths of an hour to an hour is usually a sufficient length of time to bake an ordinary sized loaf. Be careful not to remove the bread from the oven until perfectly done. It is better to allow it to bake ten minutes too long than not long enough. The crust of bread, when done, should be equally browned all over.
The common test for well-baked bread is to tap it on the bottom with the finger; if it is light and well done, it will sound hollow; heavy bread will have a dull sound. A thoroughly baked loaf will not burn the hand when lifted upon it from the pan.
CARE OF BREAD AFTER BAKING.--When done, remove the loaves from the tins, and tilt them upon edge so that the air may circulate freely on all sides of them to prevent "sweating." Do not, however, lay them on a pine shelf or table to absorb the odor of the wood. A large tin dripping pan turned over upon the table does very well to tilt them on. If they are turned often, so that they will not soften on one side, but a fine wire bread cooler is the best thing. If this is not obtainable, a fair substitute can be easily improvised by tacking window-screen wire to a light frame of sufficient size to hold the requisite number of loaves. If the bread is left exposed to the air until cold, the crust will be crisp; if a soft crust is desired, it can be secured by brushing the top of the loaf while hot, with tepid water, and covering with several thicknesses of a clean bread cloth.
If by accident any portion of the crust is burnt, grate it away as soon as cold; this is preferable to cutting or clipping it off.
BEST METHOD OF KEEPING BREAD.--When the bread is quite cold, put it away in a bread box, which should be of tin, or of wood lined with tin, convenient in form and supplied with a well-fitting cover. Never use an unlined wooden box of any kind, as it cannot easily be kept fresh and free from musty odors, which bread so readily absorbs.
Stone and earthen ware are not open to this objection, but they are likely to collect moisture, and hence are not equal to a tin receptacle. Do not keep bread in the cellar or any other damp place, nor in a close closet, where there are other foods from which it can absorb odors. The bread box should be kept well covered, and free from crumbs and stale bits. It should be carefully washed in boiling soapsuds, scalded, and dried, every two or three days. If cloths are used to wrap or cover the bread, they too should be washed and scalded every week, and oftener if at any time the loaf about which they are wrapped becomes moldy or musty.
TEST OF GOOD FERMENTED BREAD.--A loaf of good bread, well risen and perfectly baked, may be taken in the hands, and, with the thumb on the top crust and fingers upon the bottom of the loaf, pressed to less than half its thickness, and when the pressure is removed, it will immediately expand like a sponge, to its former proportions.
Good yeast bread, while it should be firm and preserve a certain amount of moisture, will, when cold, crumble easily when rubbed between the fingers. If, instead, it forms a close, soggy mass, it may be regarded as indigestible. This is one reason why hot, new yeast bread and biscuit are so indigestible. In demonstration of this, take a small lump of new bread, gently roll it into a ball, and put into a glass of water, adding a similar quantity of stale bread of the same kind also. The latter will crumble away very soon, while the former will retain its form for hours, reminding one of its condition in the stomach, "as hard as a bullet," for a long time resisting the action of the gastric juice, although, meanwhile, the yeast germs which have not been killed in the oven are converting the mass into a lump of yeast, by which the whole contents of the stomach are soured. A soluble article like salt or sugar in fine powdered form is much more easily and quickly dissolved than the same article in solid lumps, and so it is with food. The apparent dryness of stale bread is not caused by its loss of moisture; for if carefully weighed, stale bread will be found to contain almost exactly the same proportion of water as new bread that has become cold. The moisture has only passed into a state of concealment, as may be demonstrated by subjecting a stale loaf inclosed in a tightly-sealed receptacle to a temperature equal to boiling heat in an oven for half an hour, when it will again have the appearance of new bread.
Hot bread eaten with butter is still more unwholesome, for the reason that the melted grease fills up the pores of the bread, and further interferes with the action of the digestive fluids.
WHOLE-WHEAT AND GRAHAM BREADS.--The same general principles are involved in the making of bread with whole-wheat and Graham flours as in the production of bread from white flour. Good material and good care are absolutely essential.
Whole-wheat flour ferments more readily and rises more quickly than does white flour, hence bread made with it needs more careful management, as it is more liable to sour. The novice in bread-making should not undertake the preparation of bread with whole-wheat flour, until she has thoroughly mastered all the details of the art by practical experience, and can produce a perfect loaf from white flour.
Breads from whole-wheat and Graham flours require less yeast and less flour than bread prepared from white flour. A slower process of fermentation is also advantageous.
Such breads will be lighter if at least one third white flour be employed in their manufacture. When the bread is made with a sponge, this white flour may be utilised for the purpose. Thus the length of time the whole-wheat flour will be undergoing fermentation will be somewhat lessened, and its liability to become sour diminished. This plan is a preferable one for beginners in bread-making.
Graham and whole-wheat flour breads must be kneaded longer than white-flour bread, and require a hotter oven at first and a longer time for baking. Much Graham and whole-wheat bread is served insufficiently baked, probably owing to the fact that, being dark in color, the crust appears brown very soon, thus deluding the cook into supposing that the loaf is well baked. For thorough baking, from one to one and a half hours are needed, according to the size of the loaf and the heat of the oven.
TOAST.--Toasting, if properly done, renders bread more digestible, the starch being converted into dextrine by the toasting process; but by the ordinary method of preparing toast, that of simply browning each side, only the surfaces of the slices are really toasted, while the action of the heat upon the interior of the slice, it is rendered exactly in the condition of new bread, and consequently quite as indigestible. If butter is added while the toast is hot, we have all the dyspepsia-producing elements of new bread and butter combined. Although considered to be the dish _par excellence_ for invalids, nothing could be more unwholesome than such toast. To properly toast the bread, the drying and browning should extend throughout the entire thickness of the slice. Bread may be thus toasted before an open fire, but the process would be such a lengthy and troublesome one, it is far better to secure the same results by browning the bread in a moderate oven.
Such toast is sometimes called _zwieback_ (twice baked), and when prepared from good whole-wheat bread, is one of the most nourishing and digestible of foods. Directions for its preparation and use will be found in the chapter on "Breakfast Dishes."
STEAMED BREAD.--Steaming stale bread is as open to objection as the surface toasting of bread, if steamed so as to be yielding and adhesive. It is not, perhaps, as unwholesome as new bread, but bread is best eaten in a condition dry and hard enough to require chewing, that its starch may be so changed by the action of the saliva as to be easily digested.
LIQUID YEAST.
_RECIPES._
RAW POTATO YEAST.--Mix one fourth of a cup of flour, the same of white sugar, and a teaspoonful of salt to a paste with a little water. Pare three medium-size, fresh, and sound potatoes, and grate them as rapidly as possible into the paste; mix all quickly together with a silver spoon, then pour three pints of boiling water slowly over the mixture, stirring well at the same time. If this does not rupture the starch cells of the flour and potatoes so that the mixture becomes thickened to the consistency of starch, turn it into a granite-ware kettle and boil up for a minute, stirring well to keep it from sticking and burning. If it becomes too much thickened, add a little more boiling water. It is impossible to give the exact amount of water, since the quality of the flour will vary, and likewise the size of the potatoes; but three pints is an approximate proportion. Strain the mixture through a fine colander into an earthen bread bowl, and let it cool. When lukewarm, add one cup of good, lively yeast. Cover with a napkin, and keep in a moderately warm place for several hours, or until it ceases to ferment. As it begins to ferment, stir it well occasionally, and when well fermented, turn into a clean glass or earthen jar. The next morning cover closely, and put in the cellar or refrigerator, not, however, in contact with the ice. It is best to reserve enough for the first baking in some smaller jar, so that the larger portion need not be opened so soon. Always shake the yeast before using.
RAW POTATO YEAST NO. 2.--This is made in the same manner as the preceding, with this exception, that one fourth of a cup of loose hops tied in a clean muslin bag, is boiled in the water for five minutes before pouring it into the potato and flour mixture. Many think the addition of the hops aids in keeping the yeast sweet for a longer period. But potato yeast may be kept sweet for two weeks without hops, if cared for, and is preferred by those who dislike the peculiar flavor of the bread made from hop yeast.
HOP YEAST.--Put half a cup of loose hops, or an eighth of an ounce of the pressed hops (put up by the Shakers and sold by druggists), into a granite-ware kettle; pour over it a quart of boiling water, and simmer about five minutes. Meanwhile stir to a smooth paste in a tin basin or another saucepan, a cup of flour, and a little cold water. Line a colander with a thin cloth, and strain the boiling infusion of hops through it onto the flour paste, stirring continually. Boil this thin starch a few minutes, until it thickens, stirring constantly that no lumps be formed. Turn it into a large earthen bowl, add a tablespoonful of salt and two of white sugar, and when it has cooled to blood heat, add one half cup of lively yeast, stirring all well together. Cover the bowl with a napkin, and let it stand in some moderately warm place twenty-four hours, or until it ceases to ferment or send up bubbles, beating back occasionally as it rises; then put into a wide-mouthed glass or earthen jar, which has been previously scalded and dried, cover closely, and set in a cool place. Yeast made in this manner will keep sweet for two weeks in summer and longer in winter.
BOILED POTATO YEAST.--Peel four large potatoes, and put them to boil in two quarts of cold water. Tie two loose handfuls of hops securely in a piece of muslin, and place in the water to boil with the potatoes. When the potatoes are tender, remove them with a perforated skimmer, leaving the water still boiling. Mash them, and work in four tablespoons of flour and two of sugar. Over this mixture pour gradually the boiling hop infusion, stirring constantly, that it may form a smooth paste, and set it aside to cool. When lukewarm, add a gill of lively yeast, and proceed as in the preceding recipe.
BOILED POTATO YEAST NO. 2.--To one teacupful of very smoothly mashed, mealy potato, add three teaspoonfuls of white sugar, one teaspoonful of salt, and one cup of lively yeast, or one cake of Yeast Foam, dissolved in a very little water. The potatoes should be warm, but not hot enough to destroy the yeast. Allow this to stand until light, when it is ready for use.
FERMENTED BREADS.
In the preparation of breads after the following recipes, the measure of flour should be heaping.
_RECIPES._
MILK BREAD WITH WHITE FLOUR.--Scald and cool on pint of unskimmed milk. Add to the milk when lukewarm, one fourth of a cup, or three tablespoonfuls, of liquid yeast, and three cups of flour. Give the batter a vigorous beating, turn it into a clean bread bowl or a small earthen crock, cover, and let it rise over night. In the morning, when well risen, add two or three cupfuls of warm flour, or sufficient to knead. Knead well until the dough is sufficiently elastic to rebound when struck forcibly with the fist. Allow it to rise again in mass; then shape into loaves; place in pans; let it stand until light, and bake. If undesirable to set the bread over night, and additional tablespoonfuls or two of cheese may be used, to facilitate the rising.
VIENNA BREAD.--Into a pint of milk sterilized by scalding, turn a cup and a half of boiling water. When lukewarm, add one half cup of warm water, in which has been dissolved a cake of compressed yeast, and a quart of white flour. Beat the batter thus made very thoroughly, and allow it to rise for one hour; then add white flour until the dough is of a consistency to knead. Knead well, and allow it to rise again for about three hours, or until very light. Shape into four loaves, handling lightly. Let it rise again in the pans, and bake. During the baking, wash the tops of the loaves with a sponge dipped in milk, to glaze them.
WATER BREAD.--Dissolve a tablespoonful of sugar in a pint of boiling water. When lukewarm, add one fourth of a cup full of liquid yeast, and sufficient flour to make a batter thick enough to drop from the spoon. Beat vigorously for ten minutes, turn into a clean, well-scalded bread bowl, cover (wrapping in a blanket if in cold weather), and let it rise over night. In the morning, when well risen, add flour to knead. Knead well for half an hour, cover, and let it become light in mass. When light, shape into loaves, allow it to rise again, and bake.
FRUIT ROLL.--Take some bread dough prepared as for Milk Bread, which has been sufficiently kneaded and is ready to mold, and roll to about one inch in thickness. Spread over it some dates which have been washed, dried, and stoned, raisins, currants, or chopped figs. Roll it up tightly into a loaf. Let and it rise until very light, and bake.
FRUIT LOAF.--Set a sponge with one pint of rich milk, one fourth cup of yeast, and a pint of flour, over night. In the morning, add two cups of Zante currents, one cup of sugar, and three cups of flour, or enough to make a rather stiff dough. Knead well, and set to rise; when light, mold into loaves; let it rise again, and bake.
POTATO BREAD.--Cook and mash perfectly smooth, potatoes to make a cupful. Add a teaspoonful of best white sugar, one cup and a half of warm water, and when the mixture is lukewarm, one half cup of yeast, prepared as directed for Boiled Potato Yeast No. 2, and flour to make a very thick batter. Allow it to rise over night. In the morning, add a pint of warm water and flour enough to knead. The dough will need to be considerably stiffer than when no potato is used, or the result will be a bread too moist for easy digestion. Knead well. Let it rise, mold into four loaves, and when again light, bake.
PULLED BREAD.--Remove a loaf from the oven when about half baked, and lightly pull the partially set dough into pieces of irregular shape, about half the size of one's fist. Do not smooth or mold the pieces; bake in a slow oven until browned and crisp throughout.
WHOLE WHEAT BREAD.--The materials needed for the bread are: one pint of milk, scalded and cooled, one quart of wheat berry flour, one pint Minnesota spring wheat flour, one third cup of a soft yeast, or one fourth cake of compressed yeast, dissolved in one third cup of cold water. Stir enough flour into the milk to make a stiff batter, put in the yeast, and let it rise until foamy. Have the milk so warm that, when the flour is put in, the batter will be of a lukewarm temperature. Wrap in a thick blanket, and keep at an equable temperature. When light, stir in, slowly, warm flour to make a soft dough. Knead for fifteen minutes, and return to the bowl (which has been washed and oiled) to rise again. When risen to double its size, form into two loaves, place in separate pans, let rise again, and bake from three fourths to one and one half hours, according to the heat of the oven.
WHOLE-WHEAT BREAD NO. 2.--Scald one pint of unskimmed milk; when lukewarm, add one half cup of liquid yeast, or one fourth cake of compressed yeast, dissolved in one half cup of warm water, and a pint of Pillsbury's best white flour. Beat this batter thoroughly, and allow it to rise. When well risen, add three and two thirds cups of wheat berry flour. Knead thoroughly, and allow it to become light in mass; then shape into two loaves, allow it to rise again, and bake.
MISS. B'S ONE-RISING BREAD.--Sift and measure three and three fourths cups of wheat berry flour. Scald and cool a pint of unskimmed milk. When lukewarm, add one tablespoonful of lively liquid yeast. By slow degrees add the flour, beating vigorously until too stiff to use a spoon, then knead thoroughly for half an hour, shape into a loaf, place in a bread pan, cover with a napkin in warm weather, wrap well with blankets in cold weather, and let rise over night. In the morning, when perfectly light, pat in a well heated oven, and bake.
POTATO BREAD WITH WHOLE WHEAT FLOUR.--Take a half gill of liquid yeast made as for Boiled Potato Yeast No. 2, and add milk, sterilised and cooled to lukewarm, to make a pint. And one cup of well-mashed, mealy potato and one cup of white flour, or enough to make a rather thick batter Beat thoroughly, cover, and set to rise. When well risen, add sufficient whole-wheat flour to knead. The quantity will vary somewhat with the brand of flour used, but about four and one fourth cupfuls will in general be needed. Knead well, let it rise in mass and again in the loaf, and bake.
RYE BREAD.--Prepare a sponge over night with white flour as for Water Bread. In the morning, when light, add another tablespoonful of sugar, and rye flour to knead. Proceed as directed for the Water Bread, taking care to use only enough rye flour to make the dough Just stiff enough to mold. Use white flour for dusting than kneading board, as the rye flour is sticky.
GRAHAM BREAD.--Take two tablespoonfuls of lively liquid yeast, or a little less than one fourth cake of compressed yeast, dissolved in a little milk, and add new milk, scalded and cooled to lukewarm, to make one pint. Add one pint of white flour, beat very thoroughly, and set to rise. When very light, add three find one half cupfuls of sifted Graham flour, or enough to make a dough that can be molded. Knead well for half an hour. Place in a clean, slightly oiled bread bowl, cover, and allow it to rise. When light, shape into a loaf: allow it to rise again, and bake.
