We recently found out that my son is lactose intolerant. One of his favorite foods is macaroni and cheese (Kraft kind not the homemade kind). Chedder cheese is fairly free of lactose since it is a hard cheese and it is easy to find dehydrated chedder cheese. I can even find decent low lactose dried milk substitutes, but I don't have a recipe to make the mix. Does anyone have a recipe for this?
