Usually, I am the first person to walk away from anything that is "mock". But in this case, I really like this as a low fat version of Sour Cream. Place 1 cup of low fat or fat free cottage cheese in a blender with 1 tablespoon of FF Milk. Blend until smooth. This is not quite as tangy as the real thing but is great in dips, cheese cakes, and even in those jello concoctions that call for sour cream (or try it in stroganoff or paprikash) . I often make low fat versions of sauces or dips that call for sour cream when catering using this method. My customers are always aware of the switch, but the guests never have a clue and seem to enjoy everything as much or more than the high fat versions.
