- 2 large onions (2 pounds), thinly sliced
- 10 English muffins or hamburger buns, split

- Set a rack over a rimmed baking sheet.

- Working over a large bowl, gently pass the short rib through the grinder.
- Gently press the beef chuck through the grinder, gradually adding the ground short rib as you go so they are ground together.
- Gently shape the ground beef into ten 1-inch-thick patties, packing them just enough so they hold together.

- Set a cheese slice on each top half.

- Spread some caper mayonnaise on the bottom halves.

- Flip the burgers and top with half of the caramelized onions, lightly pressing them into the burger.
- Cook until browned and pink within, about 2 minutes for medium-rare.
