Ingredients
  • 1/4 cup olive oil
  • 2 red onions, thinly sliced
  • 1/2 cup sugar
  • 1/4 cup red-wine vinegar
  • 1/4 cup dry red wine, preferably syrah or zinfandel
  • 2 pound ground sirloin and chuck
  • kosher salt and freshly ground black pepper, to taste
  • 4 slices cheddar cheese
  • 4 brioche burger buns
  • sliced tomatoes
Directions
  1. Pour 2 tablespoons olive oil into a saucepan, add the onions, and sauté until they begin to wilt and sweat, taking care not to burn them. Cook for 8-10 minutes over low heat, add the sugar, and sauté for 1 minute. Carefully add the vinegar and wine, bring to a simmer, cooking until the liquid has evaporated and the onions are caramelized, approximately 3 minutes. Hold warm.
  2. Form the meat into 4 burger patties, making them tight, but not overly worked or crushed too tightly. Preheat a charcoal grill. Season each burger with salt and pepper — just before grilling
  3. Over medium-high heat, char the burgers on both sides, approximately 4 minutes per side for medium-rare; 1 or 2 minutes less or longer per side for rare or more well-done. Top the burgers with cheese, allow to melt, and serve on buns with sliced tomato and red onion jam.
