It took quite a bit of research to find a good cucumber sauce. But I think I finally found one.
We make lamb burgers often and this sauce rocks on them!
1/2 large cucumber, peeled, grated and squeezed dry
3/4 cup sour cream
1 Tbs minced mint leaves
1 tsp vinegar
1 clove garlic, minced
salt & pepper to taste
Mix cucumber, sour cream, mint, vinegar, garlic, and salt and pepper to taste in a small bowl. If you need to smoosh down and lumps with a fork only! Refrigerate sauce until ready to serve.
