Ingredients

  • 12 cup mayonnaise
  • 1 tablespoon ketchup
  • 12 teaspoon fresh lemon juice
  • 12 teaspoon prepared chili powder
  • 14 teaspoon dried chipotle powder
  • 14 teaspoon kosher salt
  • 1 14 lbs ground chuck (80% lean)
  • 6 ounces cured chorizo sausage, finely chopped (not fresh)
  • 1 teaspoon granulated garlic
  • 34 teaspoon kosher salt
  • 14 teaspoon fresh ground black pepper
  • 1 large beefsteak tomato, cut crosswise into 4 slices
  • 2 teaspoons extra-virgin olive oil
  • 4 thin slices sharp cheddar cheese
  • 4 hamburger buns, split
  • 4 leaves lettuce

Method

  • Prepare the grill for direct cooking over medium-high heat (400 to 500F).
  • In a small bowl whisk the sauce ingredients.
  • In a medium bowl gently mix the patty ingredients.
  • With wet hands, form four patties of equal size, each about 3/4 inch thick.
  • Dont compact the meat too much or the patties will be tough.
  • With your thumb or the back of a spoon, make a shallow indentation about 1 inch wide in the center of each patty.
  • This will help the patties cook evenly and prevent them from puffing on the grill.
  • Brush the tomato slices on both sides with the oil.
  • Brush the cooking grates clean.
  • Grill the patties over direct medium-high heat, with the lid closed, until they are cooked to medium doneness, 8 to 10 minutes, turning once when the patties release easily from the grate without sticking.
  • During the last 4 minutes of grilling time, grill the tomato slices over direct medium-high heat until warmed through and tender, turning once.
  • During the last minute of grilling time, place a slice of cheese on each patty to melt and toast the buns, cut side down, over direct heat.
  • Build each burger on a toasted bun with a patty, lettuce, grilled tomato, and sauce.
  • Serve warm.
