Ingredients

1. 1/4 cup plus 2 tablespoons ketchup
2. 1/4 cup mayonnaise
3. 1/4 cup finely chopped bread-and-butter pickles
4. 2 teaspoons distilled white vinegar
5. 1/2 teaspoon dry mustard
6. 1/4 teaspoon cayenne pepper
7. 1/4 teaspoon Old Bay Seasoning
8. Kosher salt and freshly ground black pepper
9. 2 pounds ground chuck
10. 4 hamburger buns, preferably brioche, split and toasted
11. Butter lettuce, sliced tomato, sliced cheddar cheese, crisp bacon and sliced avocado, for serving

1. In a medium bowl, mix the ketchup with the mayonnaise, pickles, vinegar, dry mustard, cayenne and Old Bay; season with salt and pepper. Refrigerate until ready to serve.
2. Light a grill or preheat a grill pan. In a large bowl, season the chuck with 2 teaspoons of kosher salt and 1/2 teaspoon of pepper. Gently mix the seasonings into the meat and shape into four 3/4-inch-thick patties. Grill the hamburgers over moderately high heat for about 4 minutes per side for medium-rare. Set the burgers on the buns, top with the ketchup sauce, lettuce, tomato, cheese, bacon and avocado and serve.
