Can You Use Half and Half in Place of Milk in a Recipe?

When substituting half and half, add 1/4 cup water to 3/4 cup half and half to approximate the consistency of whole milk. If there is a little milk on hand but not enough for the recipe, combine 5/8 cup of skim milk with 3/8 cup half and half to achieve the same results. The amount of combined liquid added should be equal to the amount of milk called for by the recipe.
