I got this from Everyday Food on PBS.
Homemade Barbecue Sauce
1 tbsp olive oil
1 small onion, finely chopped
4 garlic cloves, minced
1 tbsp mustard powder
1 tsp red pepper flakes
3 tbsp light brown sugar
2 cups ketchup
⅓ cup Worcestershire sauce
⅓ cup cider vinegar
1 tbsp molasses
¼ tsp ground black pepper
In a medium saucepan, heat oil over medium heat. Add onion and garlic; cook, stirring occasionally, until translucent, about 5 minutes. Stir in mustard powder and red pepper flakes; cook 30 seconds.
Reduce heat to medium low; stir in sugar, ketchup, Worcestershire, vinegar, molasses, and black pepper. Cook, stirring occasionally, until thickened, 5 to 10 minutes.
Makes 3 cups.
It is really good! I always find bottled barbecue sauce from the store way too sweet. This has a very nice tang to it. And a bit of heat too, though not too much.
I actually didn't make it exactly as written. I didn't realize it called for so much ketchup and I only had about a cup and a half. But, since I like it the way it is, I might just keep it that way!
Sorry if the picture is weird; I wasn't sure how best to photograph a sauce like this. I didn't think it would show up that well in the jar I stored it in. I wish the recipe would have stated how long it will keep in the fridge.
I used it to make barbecue chicken for barbecue chicken quesadillas.
