Bread cut or torn into small pieces and heated in a very slow oven until thoroughly dried and very delicately browned is good food for children.
The warming oven of a coal stove is about hot enough for this purpose. In the case of gas ovens it is often difficult to get the gas low enough without having the door open a little way.
The advantage of tearing instead of cutting the bread is that it makes it lighter in texture and easier to eat. The crust can be torn off from all but the ends of the loaf in one piece. This crust should be torn into pieces about two inches wide. The inside of an ordinary loaf of bread will make about 16 pieces of convenient size. Tear first across the loaf and then tear each half into eight pieces. It is usually necessary to make a small cut first in order to start the tearing. It is well to keep the crust separate, as otherwise they are likely to get too brown. Such bread will need to be reheated before being served unless it is kept in a warm place, like a warming oven.
The above is a good way to use stale bread. Some people crush it and use it with milk as a breakfast food.
