Hands down the best rub for pork that I have tried so far is Plowboys Yardbird.
For a home made rub this is pretty good also,
3/4 cup light brown sugar
1 tablespoon hickory smoked salt or 2 tablespoon kosher salt
1 tablespoon paprika
1 tablespoon garlic powder
1/2 to 1 teaspoon ground red pepper
1 tablespoon fresh ground black pepper
Howdy, partner !
I have a can of that Plowboy's coming way any day. Looking forward to it.
