This is an amazing recipe. Who would have thought mac and cheese could be so good? I made these in tiny muffins pans for my daughter's graduation party. The only reason I give this a 4 star rating is that it calls for milk sour cream but doesn't tell you how much. Last time, I must have improvised but now I'm making these again and can't remember how I made it last time. Oh well, I'll try it and see how it comes out.
