Ingredients

  • 2 cups fresh blueberries
  • 1 cup ginger beer or ginger ale
  • 1/2 cup balsamic ketchup
  • 2 tablespoons steak sauce
  • 2 tablespoons honey
  • 1 to 2 tablespoons finely chopped chipotle peppers in adobo sauce
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 2 packages (12 ounces each) Hawaiian sweet rolls
  • 3 tablespoons butter, softened
  • 3 pounds ground beef
  • 1-1/2 teaspoons salt
  • 3/4 teaspoon pepper
  • 6 slices sharp white cheddar or provolone cheese, quartered
  • 1 medium red onion, halved and thinly sliced
  • 3 plum tomatoes, thinly sliced

Method

  • In a saucepan, combine the first eight ingredients; bring to a boil. Reduce heat; simmer, uncovered, 15-20 minutes or until thickened, stirring occasionally. Cool slightly. Transfer to a food processor; process until pureed. Reserve 1/4 cup sauce for brushing burgers.
  • For sliders, split rolls horizontally in half. Spread bottoms with butter. In a large bowl, combine beef, salt and pepper, mixing lightly, but thoroughly. Shape into twenty-four 1/2-in.-thick patties, pressing an indentation in the center of each.
  • In two batches, grill burgers, covered, over medium heat 3-4 minutes on each side or until a thermometer reads 160°, brushing tops with reserved sauce after turning. Top with cheese; grill, covered, 15-30 seconds longer or until melted. Serve on rolls with onion, tomatoes and remaining sauce.
