Best rub I have found for deer,chicken, anything else is a cottage cheese bowl 3/4 full brown sugar,tbsp garlic,tbsp salt,black pepper.spoon out in a smaller bowl add whatever seasoning you want rub meat down,let set for at least 24 hrs or more.cook in smoker,grill or oven
If that 3/4 of 'a bowl' of sugar it seems like a lot of sugar, which will caramelize and burn. In my rubs I'll have equal qty or just a bit less sugar than salt. I may also add corn starch if I want a 'crust' or some other herbs spices depending on the flavor profile, like: onion powder, chili powder, cayenne, paprika, oregano, and or cardamom. 5 spice powder (not to heavy) is also good for an Asian flavor for fish, but could probably also be used on other meats.
I picked up a pretty good rub recipe a few years ago that I posted on Hunter's Gear Guide. It basically goes as follows: 1½ tsp kosher salt 1½ tsp crushed up or powdered beef bouillon 3/4 tsp garlic powder 3/4 tsp onion powder 1/2 tsp freshly ground black pepper 1/2 tsp paprika 1/2 tsp dried oregano leaves 1/2 tsp dried thyme leaves 1/4 tsp cornstarch Super good. You can check out the full recipe if you want!
Odd this just popped up again. Going to nake me a batch of Jan's Rub here shortly. Has a lot of good reviews and mentions throughout various grilling/smoking forums. https://www.smokinpetebbq.com/wordpress/jans-original-dry-rub/
