Remove peas from pods, cover with cold water, and let stand one-half hour. Skim off undeveloped peas which rise to top of water, and drain remaining peas. Cook until soft in a small quantity of boiling water, adding salt the last fifteen minutes of cooking. (Consult Time Table for Cooking.) There should be but little, if any, water to drain from peas when they are cooked. Season with butter, salt, and pepper. If peas have lost much of their natural sweetness, they are improved by the addition of a small amount of sugar.
