What spices are on the wings?
I tried a recipe that I found on America's Test Kitchen:
1 1/2 tsp corn starch (helps crisping)
1/2 tsp pepper
1 tsp chili powder
1 tsp paprika
1/2 tsp garlic powder
1/2 tsp dried oregano
1/2 tsp sugar
You will notice NO SALT. I brined the wings in 1/2 cup of salt water (2 quarts) for 30 minutes, then seasoned right before putting on the grill.
I will be using this one again. The corn starch, to me, works better than baking powder.
