This sauce is incredible on salmon. It seriously makes the best salmon I've ever tasted.
1/2 c sour cream
1/4 c mayonaise
1/4 c plain (unsweetened) yogurt
lemon juice from 1 lemon
1/2 t salt
1/2 t pepper
1/4 c finely chopped onions
1/4 c honey (or you can substitute brown sugar)
handful of fresh dill
Mix all of the above ingredients.
To make the salmon, spread the sauce generously on top of uncooked salmon filets.
