Congrats on the 4th place personal win! What a blast!
Ah, rubs. So many ways to play with them and I can't leave mine alone. What works for me, a nominal taster, doesn't work for my wife, a super taster. I lightly sprinkle ribs too and I don't wrap, but then again, you won 4th place so we should probably be taking advice from you! Here's the rub I use on my ribs that might give you some ideas.
Ray's Rib Rub for Pork
I wanted to make a homemade rub recipe that didn't have so much sugar in it. I find that I like to add the sugar at the end of a smoke to the ribs if I want them sweeter.
This is a work in progress. This recipe as written down makes enough rub to lightly sprinkle two racks of SLC spare ribs.
Result: I really liked this home created rub recipe. The SLC spareribs needed more sugar added at the end. Use turbinado or raw sugar.
1 Tbs brown sugar
2 tsp kosher salt
1 1/2 tsp sweet paprika
1 tsp course ground black pepper
1/2 tsp cinnamon
1/2 tsp cumin powder
1/2 tsp Garlic Powder
1/2 tsp onion powder
1/4 tsp cayenne pepper
1/4 tsp New Mexico chili powder
1/8 tsp mustard powder
Possible ingredients to try in 1/2 tsp amounts, making only one addition at a time to see what it does to the flavor: Allspice, cloves, nutmeg, white pepper, ginger, and sassafras.
