A treatise on the art of making good wholesome bread of wheat, oats, rye, barley and other farinaceous grains / Exhibiting the alimentary properties and chemical constitution of different kinds of bread corn, and of the various substitutes used for bread, in different parts of the world

The flour, in this case, being seldom mixed up oftener than twice, that is, the yeast previously diluted with water, is added to a part of the flour, and well kneaded; in a short time, swells and rises in the baking trough, and is called by the bakers, setting the sponge. The remainder of the flour is afterwards added, with a sufficient quantity of warm water to make it into a stiff dough, and then allowed to ferment. It is of essential consequence that the whole of the yeast should be intimately mixed with the two-thirds of the quantity of the flour put into the kneading trough, in order that the fermentation of the dough may commence in every part of the mass at the same time. The dough is then covered up, and the water which is mixed with the yeast being warm, speedily extricates air in an elastic state, and as it is now by kneading, diffused through every part of the dough, every particle must become raised, and the viscidity of the mass retains it, when it is again well kneaded and made up into loaves, and put into the oven. The heat converts the water also into an elastic vapour, and the loaf swells more and more, till at last it is perfectly porous.

During the baking, a still greater quantity of gazeous matter is extricated by the increased heat; and as the crust of the bread becomes formed, the air is prevented from escaping, the water is dissipated, the loaf rendered somewhat dry and solid, and between every particle of bread there is a particle of air, as appears from the spongy appearance of the bread.

It is curious that new flour does not afford bread of so good a quality as that which has been kept some months. The flour of grain too, which has suffered incipient germination, is much inferior in the quality of bread prepared from it: and from this principally appears to arise the injury which wheat sustains from a wet harvest. Various methods have been employed to remedy the imperfections of bread from inferior flour, such as washing the grain with hot water if it is musty, proposed by Mr. Hatchet;[^[5]] drying and heating it even to a certain extent; adding various substances, such as magnesia, &c. Some experiments on this subject have been given by Mr. E. Davy. See a Treatise on Adulterations of Food, Second Edition, p.137.

METHOD OF MAKING WHEATEN BREAD, AS PRACTISED BY THE LONDON BAKERS.

To make a sack of flour into bread, the baker pours the flour into the kneading trough, and sifts it through a fine wire sieve, which makes it lie very light, and serves to separate any impurities with which the flour may be mixed. Two ounces of alum are then dissolved in about a quart of boiling water, and the solution (technically called liquor,) is poured into the seasoning-tub. Four or five pounds of salt are likewise put into the tub, and a pailful of hot water. When this mixture has cooled to the temperature of about 84°, from three to four pints of yeast are added; the whole is mixed, strained through the seasoning sieve, emptied into a hole made in the mass of the flour, and mixed up with the requisite portion of it to the consistence of a thick batter. Some dry flour is then sprinkled over the top, and it is covered up with sacks or cloths. This operation is called setting quarter sponge.

In this situation it is left three or four hours. It gradually swells and breaks through the dry flour scattered on its surface. An additional quantity, (about one pailful,) of warm (liquor) water, in which one ounce of alum is dissolved, is now added, and the dough is made up into a paste as before; the whole is then covered up. In this situation it is left for four or five hours. This is called setting half sponge.

The whole is then intimately kneaded with more water, (about two pails full,) for upwards of an hour. The dough is cut into pieces with a knife, and penned to one side of the trough; some dry flour is sprinkled over it, and it is left to prove in this state for about four hours. It is then kneaded again for half an hour. The dough is now taken out of the trough, put on the lid, cut into pieces, and weighed, in order to furnish the requisite quantity for each loaf.

The operation of moulding is peculiar, and can only be learnt by practice; it consists in cutting the mass of dough destined for a loaf, into two equal portions: they are kneaded either round or long, and one placed in a hollow made in the other, and the union is completed by a turn of the knuckles on the centre of the upper piece.

The loaves are left in the oven about two hours and a half, or three hours, when taken out of the oven, they are turned with their bottom side upwards to prevent them from splitting. They are then covered up with a blanket to cool slowly.
