Its a rub that I have been mixing together myself for about 4 years now. I adjust it alittle here and there, depending on who will be enjoying them. It has dark brown sugar, ground black pepper, garlic powder, onion powder, granulated sugar, chilli powder, ground red pepper, paprika, ground cumin, granulated garlic, coarse sea salt(very, very little), crushed red pepper. I call this my Arizona spicy rub. Makes for some ribs that are sweet with my homemade sauce and then get a kick of heat! I tone down the heat for some people. I listed the ingredients in order from what I use the most of to the least. The way I look at it is a 3-2-1 modified mix take from the brown sugar making it 3 parts to the onion powder being 2 parts to the granulated sugar being 1 part everything adjust in between. Hope that isn't to confusing.
