3. Measuring—experiment with the cooking of starch in water; cornstarch pudding, or tapioca or sago jelly. Develop the idea of the effect of the boiling temperature on the starch grains, the bursting of the grains, and the change in flavor due to continued cooking.
4. A cereal and a fruit,—say, baked apples. In the cereal, in addition to the starch, is the cooking of the woody fibre. Note in both cereal and fruit the flavors developed by heat, the cooking being a continuation, as it were, of the ripening process.
5. A starchy and a green vegetable; as, for instance, potatoes and cabbage. Here, again, are the two principles, cookery of starch and vegetable fibre; again the development of flavor by heat. Cookery of peas and beans would better be deferred until the pupils are familiar with the effect of water on nitrogenous substances.
If time allows, a sauce may be made to serve with a vegetable, or this may be given in the next lesson.
6. Vegetable soups, without meat stock. This is in part a review lesson. Opportunity is offered here for the study of proportions, several ingredients being used, how much vegetable pulp or juice to how much liquid; how much thickening, and how much salt to a quart of soup.
7. Eggs. Experiments to show the coagulating point of the white and yolk, followed by soft and hard cooking of eggs, and possibly a plain omelet.
8. Eggs and milk.
9. Oysters.
10. Fish.
