Jamie Oliver–Style Insanity Burger

Instructions

1. Form two chuck patties slightly wider than the buns. Crinkle-cut the gherkins. Toss the sliced red onion with a splash of white wine vinegar and a pinch of salt.
2. Make the sauce by combining mayonnaise, ketchup, Worcestershire, Tabasco, bourbon and a small dribble of the onion vinegar. Stir in the finely shredded iceberg.
3. Lightly oil the patties and season with salt and pepper. Sear on the grill. After the first flip, brush the seared side with mustard. Flip again and brush the second side, then sear the mustard-coated surfaces.
4. Top with Red Leicester and cover briefly so the cheese melts. Fry the smoked bacon while the cheese melts.
5. Toast the brioche buns in the bacon fat.
6. Build each burger with sauce on the bottom bun, the cheeseburger patty, bacon, pickled onions, gherkin slices, extra ketchup and the top bun.
