I just printed off a recipe for Sweet & Sour Chicken Wings from another cooking group and it calls for GRAINY mustard. I have never seen that in any recipe before, so I have to wonder what kind of mustard would be considered grainy?

For prepared mustard, I've always go French's on hand, which is very creamy, and also Dijon Grey Poupon, and wouldn't consider that to be grainy either, so this is a puzzler. I can't see that it would make a difference in the flavor of any recipe, whether it was grainy, or smooth?
