spoonful at a time. Cut into the desired shape and drop into hot fat.
The fat should be hot enough for the dough to rise to the top instantly. * * * * * BREAD. As bread is one of the most important articles of the daily diet, it naturally follows that special attention should be given to a subject upon which the health of the family, to a great extent, depends. A knowledge of the chemical changes and their effect (see Chap. VII) must be understood before proficiency in bread-making can be attained. The first element to consider is the _yeast_, and the generating of carbonic acid gas, so as to have the bread light, tender, and porous. Yeast is a plant or vegetable growth produced from grain which has commenced to bud or sprout, and which forms the substance called diastase. This substance has the power to convert starch into sugar. (See Chap. VII for effect of yeast upon flour.) The temperature at which fermentation takes place, and when to check it, are important features of bread-making. The liquid (milk or water) should be tepid when mixed, as too great heat destroys the growth of the yeast. The dough should rise in a temperature of 75°. After fermentation has become active the temperature may be gradually lowered--as in setting bread over night--without injury. |
