Eggs are a very valuable food, because of the large amount of protein and fat they contain. Though lacking in carbohydrates, they furnish material for building up the muscles and provide heat and energy to the body. If cooked at a low temperature, eggs are very easily and very completely digested. Combined with other foods, they serve as a thickening agent (for sauces and soups) and as a means of making batters light (popovers and sponge cake). They add flavour and colour and increase the nutritive value of other foods.
PRELIMINARY PLAN
The lesson on eggs furnishes one of the best opportunities to teach the muscle-building foods. If eggs are scarce, it may be well to give this lesson at some other time. Each pupil should be asked to bring an egg; one or two should bring a little milk; and sufficient bread should be provided to toast for the poached eggs. The teacher should not undertake to give too many recipes in this lesson, but should try to make the pupils familiar with a sufficient variety of ways of using eggs to make egg cookery interesting. The necessity of having a moderate temperature for the cooking of eggs should be emphasized.
RECIPES
Soft-cooked Eggs
Put the eggs in boiling water sufficient to cover them, remove from the fire, cover, and allow them to stand from 5 to 8 minutes.
Hard-cooked Eggs
Put the eggs in cold water, heat, and, when the water boils, reduce the heat, and let them stand for 20 minutes with water just below the boiling-point, then put them into cold water.
Poached Eggs
Break each egg into a saucer carefully, slip the egg into boiling water, decrease the heat, and cook for 5 minutes, or until the white is firm and a film has formed over the yolk. Take up with a skimmer, drain, trim off the rough edges, and serve on slices of toast. Season.
