Two large handfuls of hops are boiled in four quarts of water: this is poured upon as much wheaten bread as it will moisten, and to this are added four or five pounds of leaven. When the mass is warm, the several ingredients are worked together till well mixed. It is then deposited in a warm place for twenty-four hours, and afterwards divided into small pieces, about the size of a hen’s egg, which are dried by being placed on a board, and exposed to a dry air, but not to the sun; when dry, they are laid up for use, and may be kept half a year. The ferment, thus prepared, is applied in the following manner: for baking six large loaves, six good handfuls of these balls are dissolved in seven or eight quarts of warm water; this water is poured through a sieve into one end of the bread trough, and after it three quarts of warm water; the remaining mass being well pressed out. The liquor is mixed up with flour, sufficient to form a mass of the size of a large loaf; this is strewed over with flour: the sieve, with its contents, is put upon it, and the whole is covered up warm, and left till it has risen enough, and its surface has begun to crack; this forms the leaven. Fifteen quarts of warm water, in which six handfuls of salt has been dissolved, are then poured upon it through the sieve; the necessary quantity of flour is added, and mixed and kneaded with the leaven: this is covered up warm, and left for about half an hour. It is then formed into loaves, which are kept for another half-hour in a warm room; and after that they are put into the oven, where they remain two or three hours, according to their size. ------------------------------------------------------------------------ Bread made with Yeast. The principal improvement that has been made in the art of fabricating bread, consists in the substitution of yeast, (or the froth that rises to the surface during the fermentation of malt liquors,) instead of common flour dough, in a state of acescency, called _leaven_, to rise the bread dough, made of flour and water, before it is baked. This substance very materially improves the bread. Yeast makes the dough rise more effectually than ordinary _leaven_, and the bread thus produced is much lighter, and free from that sour taste which may often be perceived in bread raised with leaven; because too much has been added to the paste, or because the dough has been allowed to advance too far in the process of fermentation before it was baked. The discovery of the application of yeast, to improve the panification of bread flour, was made and first secretly adopted by the bakers of Paris; but when the practice was discovered, the College of Physicians there, in 1688, declared it prejudicial to health, and it was not till after a long time that the bakers succeeded in convincing the people, that bread made with yeast was superior to bread made with sour dough or leaven.
