COOKING HINTS Put left-over stew of any kind into individual baking dishes or casseroles, cover with a biscuit or plain pie crust and bake. Always cook fish at a low to moderate temperature. Never more than 350 degrees F. Broiled tomatoes, sprinkled with a little grated: cheese, while cooking, are delicious. Tomatoes scalded with hot water, may be peeled easily. Add a little sugar to all vegetables when cooking to bring out natural flavor. Leafy vegetables, such as spinach, chard, kale, etc., should be slowly cooked in only the water that clings to the leaves. Shredded grapefruit is a delightful addition to any fish salad. Fried pies, an old Southern delicacy, are made by folding pastry over chopped sweetened fruit and frying in deep fat. Brush over the bottom crust for fruit pies with egg white to prevent the juices from soaking in. l
