Can I use water instead of milk for Kraft?
You could use water instead of milk in macaroni and cheese, but the result would likely be runnier and lack the full flavor macaroni and cheese is supposed to have. You can also go the other way, to increase the flavor; omit the milk and double the amount of butter, using real butter instead of margarine.
