Season them with Paprika,Onion Powder,and a bit of Chili Powder(not red pepper).......then rub it in with yellow mustard. You will not taste the mustard when the ribs are done. I like Mcormicks Seasonings.
I can not use most, if any premixed spices.....the salt is a big reason behind this.......
I have become very good at marinading meats and mixing that with different woods for smoking purposes.
The main spice combination I have used came from emeril where I leave out the salt and short the hotter spices.
