Preheat oven to 450 degrees F. I was recently introduced to SUMAC THROUGH THE USE OF A RECIPE FOUND HERE AT JUST A PINCH. It is used in Mediterranean, Indian, & Lebanese cooking and often is substituted for Lemon or Vinegar. It can be added to marinades, soups dips, stews, salad dressings rice and various different casseroles. Need more Info then Google or Bing it. Since I ordered it, and have quite a bit, I decided to find new and creative ways to use it, and this is one of my first recipes using it.
