Question: how much egg white equals one whole egg?
Answer: When reducing eggs in a from-scratch recipe, substitute 2 egg whites or 1/4 cup fat-free egg substitute for 1 whole egg. It's best to leave at least 1 whole egg in the recipe. One large whole egg has 75 calories, 5 grams fat, 1.6 grams saturated fat and 213 mg cholesterol.
