LEAVENING AGENTS
The handling of the ingredients and the mixture has also much influence on the success with which
hot breads are produced. A heavy touch and excessive handling, both of which are usually characteristic of the beginner, are more likely to result in a tough product than is the light, careful handling of the expert.
However, as skill in this matter comes with practice, no discouragement need result if successful
results are not forthcoming at the very start in this work. A good rule to follow in this particular, and one that has few exceptions, is to handle and stir the ingredients only enough to blend them properly.
In addition to the matters just mentioned, the utensils in which to combine the hot-bread materials and bake the batters or doughs are of importance. While none of these is complicated, each must be of the right kind if the best results are expected. The final point to which attention must be given is the baking of this food. Proper baking requires on the part of the housewife familiarity with the oven that is to be used, accuracy in judging temperature, and a knowledge of the principles underlying the process of baking.

CLASSES OF LEAVENING AGENTS
3. As has been pointed out, the ingredients that are actually required in the making of hot breads are flour, liquid, salt, and leavening, and to give variety to breads of this kind, numerous other materials, including sugar, shortening, eggs, fruit, nuts, etc., are often added. With the exception of leavening agents, none of these ingredients requires special attention at present; however, the instruction that is given in Bread regarding flour should be kept in mind, as should also the fact that all the materials for hot breads should be of the best quality that can be obtained.
As is known by this time, leavening agents are the materials used to leaven, or make light, any kind of flour mixture. These agents are of three classes, namely, organic, physical, and chemical. The organic agent is the oldest recognized leavening material, it being the one that is used in the making of yeast breads; but as a complete discussion of this class of leavening agents is given in Bread and as it is not employed in the making of hot breads, no consideration need be given to it here.
Physical leavening is accomplished by the incorporation of air into a mixture or by the expansion of the water into steam, and chemical leavening agents are the most modern and accurate of all the agents that have been devised for the quick rising of flour mixtures.
