I have never been a big fan of chicken quarters but have used this recipe a few times and now love them. It's simple and very good. Took some quarters and thighs to a party and everybody raved over it. Few said it was the best chicken they ever ate.
8 cups water
3/4 cup kosher salt
3/4 cup brown sugar
3/4 cup white vinegar
1 Tbs. poultry seasoning (I used creole seasoning)
Mix all ingredients till dissolved and brine for around 5 hours. I like using Glad 2 1/2 gallon Zip lock bags to brine chicken in.
Pull out of brine, rinse off brine, coat with extra virgin olive oil, season very well with favorite rub. Cook indirect. Sauced at end of cook.
