Tomato Sauce/Juice

Since many classic recipes call for tomato juice or tomato sauce, it's good to know that you can make your own rather than rely on the canned varieties that contain additives. To make tomato juice, simply purée tomatoes in a blender, add lemon juice and salt. Strain the mixture for juice and retain the pulp and a little juice to use in recipes calling for tomato juice.
