My cousin is a heck of a barbecue cook! And we've always loved his BBQ sauce. I decided to ask him for his recipe, thinking he might not want to share it. But it turns out it was a recipe he had found in a book (sorry I can't give credit to the original author of the recipe). And it's pretty customizable. You can change the type of vinegar or mustard, use more or less Tabasco for heat and whatever barbecue rub you use will have an impact on the sauce as well.
Use it on literally anything!
2 cups ketchup
1/4 cup cider vinegar
1/4 cup Worcestershire sauce
1/4 cup firmly packed brown sugar
2 tbsps molasses
2 tbsps prepared mustard
1 tbsp Tabasco sauce
1 tbsp of your favourite BBQ rub
2 tsps liquid smoke
1/2 tsp black pepper
Combine everything in a saucepan and bring to a boil over medium to medium high heat, then reduce the heat to a simmer for 15 minutes. Pour into sterilized jars and store in the fridge for months (if it lasts that long!)Makes 2 1/2 cups
