1/2 Lb Pasta
Combine pasta, peas, carrots, shrimp, pickles, capers, and Old Bay. Add mayo and sour cream and mix thoroughly. Add chopped dill a little at a time being sure not to use too much. Salt & pepper to taste. I don't use salt because the pickles and capers usually have plenty.
You might vary the recipe depending on how long it will be before serving. The pasta really sucks up the sauce, so you might use more mayo/sour cream if it will be a while before serving.
