I always put some in my bbq sauce.
Mince some onions (about 1 cup)
and some garlic ( about 6 cloves)
and saute in two or three tablespoons of olive oil
just until soft.
Add 4 tablespoons brown sugar
2 tablespoons yellow mustard
2 teaspoons worcestershire sauce (or more if you want)
1/2 teaspoon crushed red pepper ( more or less to taste)
salt and pepper to taste.
mix well and cook for 5 minutes or so.
All amounts are really up to you.
I make it differently every time I make it.
