What is a good substitute for skim milk?
Use any of these substitutes in equal proportions to the skim milk they replace in a recipe. While all the dairy milks have a similar taste and texture to skim milk, the non-dairy milks all have a unique flavor based on what they are made from. While one may taste good in cereal or for drinking, it may impart unwanted flavors in other dishes or desserts. Source: godairyfree.org
