I make a few bbq sauces, my favorite is kind of a sweet/hot one goes like this..

16 oz ketchup
1 cup brown sugar
1 t salt
1 t garlic salt
1 t black pepper
1 t whorecherstir (I can't say it or spell it) sauce
1 t liquid smoke

Just heat it up on stove to dissolve everything

This bbq sauce has always gotten great comments from friends and people who have eatten it
