- 12 slices good-quality smoky bacon
Pre-heat the oven to 350°F.
Par-bake the bacon for 10 minutes on a slotted pan or on cooling rack set over baking sheet to render some of the fat. Cool to handle.
Combine the barbecue sauce ingredients in a small pot. Bring to a bubble and reduce the heat to low; cook for 15-20 minutes to thicken.
Place the onion rings in a bowl and dress with salt, pepper and lime juice.
Combine the meat with the chipotle, Worcestershire sauce, salt, pepper and a drizzle of oil. Form six patties.
Heat a double-burner griddle or flat side of a grill pan over medium to medium-high heat.
Cross two slices of bacon on a work surface like an X, then place a burger pattie on top of the X and wrap bacon up and around burger. Repeat to wrap all six burgers. Cook the burgers seam-side down until the bacon is crisp, about 6 minutes. Flip and cook the burgers for six minutes more. Top the burgers with cheese in last minute or so; cover with a loose foil tent to melt.
Arrange a little lettuce on the bun bottoms and top with the burger patties, barbecue sauce, onions and bun tops.
