A Treatise on Bread, and Bread-making
Part 4
Another way by which yeast when thus made may be preserved much longer, and perhaps more conveniently, is, to take it when it has become perfectly light, and stir in good Indian meal until it becomes a hard dough: then take this dough and make it into small thin cakes, and dry them perfectly, without baking or cooking them at all. These cakes, if kept perfectly dry, will be good for several weeks and even months.
When yeast is needed, take some of these cakes (more or less according to the quantity of bread desired) and break them fine and dissolve them in warm water, and then stir in some wheat flour till a batter is formed, which should be kept at a temperature of about 60° F. till the yeast becomes light and lively, and fitted for making bread.
Others, in making this yeast, originally put into the water with the hops, a double handful of good clean wheat bran, and boil them up together and strain off the water as above described: others again, boil up a quantity of wheat bran without the hops, and make their yeast in all other respects as above described.
The milk yeast is greatly preferred by many; and when it is well managed, it certainly makes very handsome bread. The way of making it is simple. Take a quart of milk fresh from the cow, (more or less according to the quantity of bread desired,)—a little salt is generally added, and some add about half a pint of water blood warm, but this is not essential;—then stir wheat flour or meal into the milk till it forms a moderately thick batter; and then cover it over, and place it where it will remain at a temperature of from 60° to 70° F. till it becomes perfectly light. It should then be used immediately: and let it be remembered that dough made with this yeast will sour sooner than that made with other yeast; and also that the bread after it is baked will become extremely dry and _crumbly_ much sooner than bread made with other yeast. Yet this bread, when a day old, is exceedingly light and beautiful: albeit some dislike the animal smell and taste which it derives from the milk.
In all these preparations of yeast and dough, it should ever be recollected that “the process of fermentation cannot go on when the temperature is below 30° F., that it proceeds quite slowly at 50°, moderately at 60°, rapidly at 70°, and very rapidly at 80°.”
If, therefore, it is desired to have the yeast or dough stand several hours before it is used or baked, it should be kept at a temperature of about 50°. But in the ordinary way of making bread, a temperature varying from 60° to 70°, or about summer heat, is perhaps as near right as it can well be made.
Prof. Thomson gives the following directions for making yeast in large quantities:—“Add ten pounds of flour to two gallons of boiling water;—stir it well into a paste, let this mixture stand for seven hours, and then add about a quart of good yeast. In about six or eight hours, this mixture, if kept in a warm place, will have fermented and produced as much yeast as will make 120 quartern loaves” (of 4 lbs. each.)
A much smaller quantity can be made by observing due proportions of the ingredients.
To raise bread in a very short time without yeast, Prof. Thomson gives the following recipe:
“Dissolve in water 2 ounces, 5 drams and 45 grains of common crystallized carbonate of soda, and mix the solution well with your dough, and then add 7 ounces, 2 drams and 22 grains of muriatic acid of the specific gravity of 1,121, and knead it as rapidly as possible with your dough;—it will rise immediately—fully as much, if not more than dough mixed with yeast—and when baked, will be a very light and excellent bread.” Smaller quantities would be required for small batches of bread.
A tea-spoonful or more (according to the quantity of dough or batter) of super-carbonate of soda dissolved in water, and flour stirred in till it becomes a batter, and then an equal quantity of tartaric acid dissolved and stirred in thoroughly, will in a few minutes make very light batter for griddle or pancakes; or if it be mixed into a thick dough, it will make light bread.
Good lively yeast, however, makes better bread than these alkalies and acids: howbeit these are very convenient in emergencies, when bread or cakes must be prepared in a very short time; or when the yeast has proved inefficient.
We see then that wheat meal consists of certain proportions of starch, gluten, sugar, bran, &c.; and that in making loaf bread, we add yeast or leaven, in order to produce that kind of fermentation peculiar to saccharine matter or sugar, which is called vinous, and by which the gas or air is formed that raises the dough. But the sugar is an incorporate part of every particle of the meal, and is therefore equally diffused throughout the whole mass; and hence if we would make the very best loaf bread, the fermentive principle or yeast must also be equally diffused throughout the whole mass, so that a suitable portion of yeast will be brought to act at the same time on every particle of saccharine matter in the mass.
But let us endeavor to understand this process of fermentation. To speak in the language of chemistry, sugar is composed of certain proportions of carbon, oxygen and hydrogen. The yeast, acting on the sugar, overcomes those affinities by which these substances are held in the constitutional arrangement of sugar, and the process of decay or decomposition of the sugar takes place, which is called vinous fermentation. By this process of decay, two other forms of matter are produced, of an essentially different nature from each other and from the sugar. One of them is called carbonic acid gas or air, being formed by a chemical combination of certain proportions of carbon and oxygen. The other is known by the name of alcohol, and consists of a chemical combination of certain proportions of carbon, oxygen, and hydrogen. Carbonic acid gas is also produced by animal respiration or breathing, by the combustion of wood, coal, &c. &c. and in other ways of nature and of art: but neither in nature nor in art is there any known way by which alcohol can be produced, except by that process of the decay or destruction of sugar called vinous fermentation.
The carbonic acid gas, produced in the manner I have stated, is the air which inflates or puffs up and swells out the bread, when there is sufficient gluten or other cohesive matter in the dough to prevent its escape.
If the dough be permitted to stand too long in a warm place, the fermentation, having destroyed most or all of the sugar, will begin to act on the starch and mucilage, and destroy their nature, and produce vinegar; and therefore this stage of it is called the acetous fermentation: and if it still be permitted to go on, it will next commence its work of destruction on the gluten; and this is called the putrefactive fermentation, because it in many respects resembles the putrefaction of animal matter.
The vinous fermentation, therefore, by which the dough is raised and made light, may be carried to all necessary extent, and still be limited in its action to the saccharine matter or sugar—leaving the starch and gluten, and other properties of the meal, uninjured; and this is the point at which the fermentation should be arrested by the heat that bakes the dough. If it be permitted to go beyond the sugar, and act on the mucilage and starch, and produce acidity, the excellence of the bread is in some degree irreparably destroyed. The acid may be neutralized by pearlash or soda, so that the bread shall not be sour; but still, something of the natural flavor of the bread is gone, and it is not possible by any earthly means to restore it; and this injury will always be in proportion to the extent to which the process of the acetous fermentation is permitted to go in destroying the nature of the starch, and the bread will be proportionably destitute of that natural sweetness and delicious richness essential to good bread. Yet it is almost universally true, both in public and domestic bread-making, that the acetous fermentation is allowed to take place; and saleratus, or soda, or some other chemical agent is employed to neutralize the acid. By this means we may have bread free from acidity, it is true, but it is also destitute of the best and most delicious properties of good bread; and generally, by the time it is twenty-four hours old—and this is particularly true of bakers’ bread—it is as dry and tasteless and unsavory as if it were made of plaster of Paris.
Many bread-makers mix their saleratus or soda with their yeast, or introduce it when they mix their dough, so that if the acetous fermentation does take place, the acid is neutralized by the alkali, and therefore, not being perceived, it is supposed never to have existed, and the bread is called sweet and good; especially if a small quantity of molasses be employed in making the dough. Others far more wisely withhold their alkali till the dough is raised enough to mould into the loaf, and then if it is found to be in any degree acid, a solution of saleratus or soda is worked into it, so as just to neutralize the acid, and no more. This is infinitely better that no have sour bread, which, after all, is almost everywhere met with; yet the very best bread that can be made in this way is only second best. Happy are they who can make good light and sweet bread, without the use of molasses—without suffering the least degree of acetous fermentation to take place, and without employing saleratus, soda, or any other kind of alkali.
The third or putrefactive stage of fermentation rarely takes place in domestic bread-making; but it is by no means uncommon in public bakeries. Indeed it is thought necessary in the manufacture of certain kinds of crackers, in order to make them split open, and render them brittle, and cause them readily to become soft when dipped into water. But dyspepsia crackers, and all other kinds of bread made in this way are, to say the least of them, miserable stuff. For besides the fact that all the best qualities of the flour or meal have been destroyed by fermentation, the great quantity of alkali employed in neutralizing the acid, is necessarily injurious to the digestive organs.
PREPARATION OF BREAD.
Mixing. Much kneading necessary. Rising, or fermentation. Use of alkalies, saleratus and soda. Baking. Ovens. Alcohol in bread. Preservation of bread.
Now, then, the business of the bread-maker is, to take the wheat meal, prepared in the manner I have stated, and with all the properties I have described, and convert it into good, light, sweet, well-baked bread, with the least possible change in those properties; so that the bread, when done, will present to the senses of smell and taste, all the delicious flavor and delicate sweetness which pure organs perceive in the meal of good new wheat, just taken from the ear and ground, or chewed without grinding; and it should be so baked that it will, as a general statement, require and secure a full exercise of the teeth in mastication.
In order to do this, as we have seen, it is necessary, in the first place, that the wheat should be of the best kind, and well cleansed, and the meal properly prepared. In the next place, it is necessary that the yeast should be fresh, lively and sweet; and in the third place, it is necessary that the dough should be properly mixed, raised and baked.
Take then such a quantity of meal, in a perfectly clean and sweet bread trough, as is necessary for the quantity of bread desired, and having made a hollow in the centre, turn in as much yeast as a judgment matured by sound experience shall deem requisite; then add such a quantity of water, milk and water, or clear milk, as is necessary to form the meal into a dough of proper consistency. Some prefer bread mixed with water alone; others prefer that which is mixed with milk and water; and others think that bread mixed with good milk is much richer and better; while others dislike the animal odor and taste of bread mixed with milk. Perhaps the very best and most wholesome bread is that which is mixed with pure soft water, when such bread is made perfect. But whether water, milk and water, or milk alone is employed, it should be used at a temperature of about blood heat.
Here let it be understood, that the starch of the meal is of such a nature that, by a delicate process peculiar to itself, it becomes changed into sugar or saccharine matter; and when the fluid used in mixing the dough is of a proper temperature, and the dough is properly mixed and kneaded, this process, to some small extent, takes place, and a small portion of the starch is actually converted into sugar, and thereby increases the sweetness of the bread. Let it also be recollected here, that the saccharine matter on which the yeast is to act, is equally diffused throughout the whole mass of the meal; and therefore if the yeast be not properly diffused throughout the whole mass, but is unequally distributed, so that an undue quantity of it remains in one part, while other parts receive little or none, then the fermentation will go on very rapidly in some parts of the mass, and soon run into the acetous state, while in other parts it will proceed very slowly or not at all; and consequently large cavities will be formed in some parts of the dough, while other parts of it will remain as compact and heavy as when first mixed, and sometimes even more so. I need not say that such dough cannot be made into good bread; yet it is probably true, that more than nine tenths of the bread consumed in this country is more or less of this character. Nor, after what I have said, should it seem necessary for me to remark, that good bread cannot be made by merely stirring the meal, and yeast, and water or milk together into a thin dough or sponge, and suffering it to ferment with little or no working or kneading. Bread made in this manner, if it is not full of cavities large enough for a mouse to burrow in, surrounded by parts as solid as lead, is almost invariably full of cells of the size of large peas and grapes; and the substance of the bread has a shining, glutinous appearance; and if the bread is not sour, it is because pearlash or some other kind of alkali has been used to destroy the acid.
The very appearance of such bread is forbidding, and shows, at a glance, that it has not been properly mixed—that the yeast has acted unequally on different portions of the meal, and that the fermentation has not been of the right kind.
But if the yeast be so diffused throughout the whole mass, as that a suitable portion of it will act on each and every particle of the saccharine matter at the same time, and if the dough be of such a consistency and temperature as not to admit of too rapid a fermentation, then each minute portion of saccharine matter throughout the whole mass will, in the process of fermentation, produce its little volume of air, which will form its little cell, about the size of a pin’s head, and smaller; and this will take place so nearly at the same time, in every part of the dough, that the whole will be raised and made as light as a sponge, before the acetous fermentation takes place in any part. And then if it be properly moulded and baked, it will make the most beautiful and delicious bread—perfectly light and sweet, without the use of any alkali, and with all the gluten and nearly all the starch of the meal remaining unchanged by fermentation.
Proper materials, proper care, a due amount of labor, a suitable length of time, and proper temperature, are all, therefore, necessary to the making of good bread.
With your meal, and yeast, and water or milk brought together before you, then, proceed in the light of the instruction you have now received, to mix your dough; and remember that the more thoroughly you knead it, the more equally you diffuse the yeast throughout the whole mass, and bring it to act on every particle of the saccharine matter at the same time, and the whiter, lighter, and more delicious you make your bread.
Who that can look back thirty or forty years to those blessed days of New England’s prosperity and happiness, when our good mothers used to make the family bread, but can well remember how long and how patiently those excellent matrons stood over their bread troughs, kneading and moulding their dough? and who with such recollections cannot also well remember the delicious bread that these mothers used invariably to set before them? There was a natural sweetness and richness in it which made it always desirable; and which we cannot now vividly recollect, without feeling a strong desire to partake again of such bread as our mothers made for us in the days of our childhood.
Let it be borne in mind, then, that without a very thorough kneading of the dough, there can be no just ground of confidence that the bread will be good. “It should be kneaded,” says one of much experience in this matter, “till it becomes flaky.” Indeed I am confident that our loaf bread would be greatly improved in all its qualities, if the dough were for a considerable time subjected to the operations of the machine which the bakers call the break, used in making crackers and sea-bread.
The wheat meal, and especially if it is ground coarsely, swells considerably in the dough, and therefore the dough should not, at first, be made quite so stiff, as that made of superfine flour; and when it is raised, if it is found too soft to mould well, let a little more meal be added.
When the dough has been properly mixed and thoroughly kneaded, cover it over with a clean napkin or towel, and a light woollen blanket kept for the purpose, and place the bread trough where the temperature will be kept at about 60° F., or about summer heat, and there let it remain till the dough becomes light. But as it is impossible to regulate the quantity and quality of your yeast, the moisture and temperature of your dough, and several other conditions and circumstances, so as to secure at all times precisely the same results in the same time, it is therefore necessary that careful attention should be given that the proper moment should be seized to work over and mould the dough into the loaf, and get it into the oven, just at the time when it is as light as it can be made by the vinous fermentation, and before the acetous fermentation commences.
If, however, by any means there should unfortunately be a little acidity in the dough, take a small quantity of saleratus, or, what is better, carbonate of soda, and dissolve it in some warm water, and carefully work in just enough to neutralize the acid. The best bread-makers are so exceedingly careful on this point, that they dip their fingers into the solution of saleratus or soda, and thrust them into the dough in every part, as they work it over, so as to be sure that they get in just enough to neutralize the acid, and not a particle more.
I must here repeat, that they who would have the very best of bread, must always consider it a cause of regret, that there should be any necessity to use alkali; because the acetous fermentation cannot in any degree take place, without commensurately and irremediably impairing the quality of the bread. And here it should be remarked, that dough made of wheat meal will take on the acetous fermentation, or become sour, sooner than that made of fine flour. This is probably owing principally to the mucilage contained in the bran, which runs into the acetous fermentation sooner than starch.
While the dough is rising, preparations should be made for baking it. Some bake their bread in a brick oven, some in a stove, some in a reflector, and some in a baking kettle. In all these ways very good bread may be baked; but the baking kettle is decidedly the most objectionable. Probably there is no better and more certain way of baking bread well than in the use of the brick oven. Good bread-makers, accustomed to brick ovens, can always manage them with a very great degree of certainty; and as a general fact, bread is sweeter, baked in this way, than in any other. Yet, when it is well baked in tin reflectors, it is certainly very fine; and so it is also when well baked in iron stoves. But the baking of bread requires almost as much care and judgment as any part of the process of bread-making. If the oven is too hot, the bread will burn on the outside before it is done in the centre; if it is too cold, the bread will be heavy, raw and sour. If the heat is much greater from below than from above, the bottom of the loaf will burn before the top is done: or if the heat is much greater from above than from below, the top of the loaf will burn before the bottom is done.
All these points therefore must be carefully attended to; and no small excuse ought to be considered a satisfactory apology for sour, heavy, raw or burnt bread; for it is hardly possible to conceive of an absolute necessity for such results; and the cases are extremely rare in which they are not the offspring of downright and culpable carelessness.
The best bread-makers I have ever known, watch over their bread troughs while their dough is rising, and over their ovens while it is baking, with about as much care and attention as a mother watches over the cradle of her sick child.
Dough made of wheat meal requires a hotter oven than that made of fine flour; and it needs to remain in the oven longer. Indeed, it is a general fault of bread of every description, made in this country, that it is not sufficiently baked. Multitudes eat their bread hot and smoking from the oven in a half-cooked state; and very few seem to think there is any impropriety in doing so. But they who would have their bread good, not only a few hours after it comes from the oven, but as long as it can be kept, must see that it is thoroughly baked.
I have said that the process of vinous fermentation converts a portion of the saccharine matter of the meal into carbonic acid gas or air, by which means the dough is raised and made light; and that the same process converts a portion of the saccharine matter into alcohol. The alcohol thus generated is mostly if not entirely driven off by the heat of the oven when the dough is baking;—and in modern times, ovens have been so constructed in England, as to serve the double purpose of ovens and stills; so that while the bread is baking, the alcohol is distilled off and condensed, and saved for the various uses of arts and manufacture.
The question has, however, been frequently started, whether a portion of the alcohol thus generated, is not contained in the bread when it comes from the oven.
This question cannot be answered with entire certainty; but there are some facts in relation to it of considerable importance.
It is perfectly certain that if two portions of wheat meal or flour be taken from the same barrel or sack, and one portion be made into unleavened bread, and the other portion be made into the very best fermented or raised bread, and both be eaten as soon as they are baked, the fermented bread will digest with more difficulty, and oppress and disturb the stomach more than the unleavened bread will. Indeed it is well known and very generally understood, that few of the articles which compose the food of man in civic life, are so trying to the human stomach, and so powerful causes of dyspepsia, as fresh-baked raised bread.
