Make-Ahead: Barbecue sauce can be made up to 3 days ahead, covered and refrigerated.
1/2 cup ketchup
2 tbs. Dijon mustard
2 tbs. light brown sugar
2 tbs. molasses
2 tbs. unsalted butter
2 tbs. Worcestershire sauce
1 tbs. apple cider vinegar
1 chipotle chile in adobo, finely chopped
Four 5-oz. frozen beef burger patties
1 tbs. olive oil
4 hamburger buns, toasted
1 dill pickle, thinly sliced
1/4 white onion, thinly sliced
- In small ovenproof saucepan, whisk ketchup, mustard, sugar, molasses, butter, Worcestershire, vinegar, and chipotle. Place over medium heat and cook sauce, stirring occasionally, for 5 minutes, or until it has thickened slightly. Season with salt and pepper.
- Prepare grill for medium-high heat.
- Season patties with salt and pepper. Grill frozen patties about 4 minutes. Turn patties over, brush with some barbecue sauce, and grill about 4 minutes for medium-rare doneness.
