Substitute an equal amount of sour cream for milk in a recipe. Examine the texture of the sour cream. Adjust the level of shortening or butter in the recipe. Reduce the shortening by 1/2 cup for thick or heavy sour cream or 1/3 cup for thin or light sour cream.
Light, or reduced-fat, sour cream contains less butterfat than regular sour cream, because it is made from a mixture of milk and cream rather than just cream. Fat-free sour cream contains no cream at all, and is made primarily from non-fat milk, modified cornstarch, thickeners and flavoring agents.ight, or reduced-fat, sour cream contains less butterfat than regular sour cream, because it is made from a mixture of milk and cream rather than just cream.
