You can never have too many marinade ideas for barbecuing! The good thing about dry rubs is that you can easily carry them anywhere, and won't go bad - perfect for camping! Here is my favorite dry rub recipe for Portugese BBQ Chicken, right from my backyard.
Gather the following: For a kilogram of bone-in chicken (I went with chicken drumsticks), you'll need 2 tablespoons of sweet paprika, 2 tablespoons of dried oregano, 2 tablespoons of garlic powder, 1 tablespoon of onion powder, 1 tablespoon of cumin powder, a teaspoon of brown sugar, 2 tablespoons of cayenne pepper powder, ground 1/2 bay leaf, a pinch of cinnamon, 1 teaspoon of lemon rind, and salt and black pepper to your discretion.
Mix together and apply with a little olive oil to skin-on, bone-in chicken, and let sit for a bit before chucking them on the nearest BBQ you can find!
