Sometimes when I have some chicken (parts or whole) to grill, I don't feel like or have time to make a rub for it. I used Old Bay Seasoning at one of these times and it has become one of our favorite rubs. I put a generous coating on the skin and on the meat side of parts, and on and under the skin of a whole chicken. Delicious!
I also use Emeril's Essence as a rub. It's easy for me because I always keep some around for other dishes. Don't buy it, make your own from the recipie available with almost all of Emeril's recipies on www.foodtv.com or on www.emeril.com.
