How Do You Substitute Milk in a Recipe?

When substituting other liquids for milk, cooks can generally use a ratio of 1 cup milk to 1 cup of the substitute. When substituting skim or low-fat milk for whole milk, add 1 tablespoon of melted better to each cup of milk to achieve an equivalent fat content. Cooks should mix evaporated milk with water before using it in a recipe at a ratio of 2/3 cup evaporated milk and 1/3 cup water for each cup of milk.
