Behind the fence in the backyard is completely overgrown with blackberries which means a freezer full of blackberry jam every summer! The best way to get rid of the extra is to make Blackberry BBQ Sauce.
1 cup ketchup
3 Tablespoons brown sugar
1/3 cup blackberry jam
1 teaspoon mustard
1 Tablespoon red wine vinegar
Mix it in a small bowl. Use as you would any other BBQ sauce.
I poured mine over a beef roast in the crock pot and cooked it on low for 8-10 hours or high for 4-6 hours.
Shred the beef and serve on hamburger buns.
