825 grams minced beef
500 grams minced venison
Shio Kombu (see separate recipe)

26 grams kosher salt

Sliced cheese
Burger buns, toasted
Half-sour pickle spears
Sliced onion
Ketchup

Notes

825 grams chuck steak, preferably wagyu, cut into 1-inch chunks
540 grams boneless short rib, cut into 1-inch chunks

Salt is vital to the structure of a meatball, meat loaf, or burger patty. In addition to seasoning the meat, it roughs up the proteins, allowing them to bind together.

Combine the beef mince, venison mince, shio kombu, milk powder and salt.
Mix thoroughly.
Refrigerate for 8 hours or up to overnight. (This resting time helps the umami flavour of the seaweed work its way into the burger meat.)
Form into 100gm balls and flatten into 1 cm thick patties.

Sear the burgers on a scorching hot barbeque.
Put the cheese on the patties to melt a bit before removing them from the grill.
Let the burgers rest a minute or two before putting them between toasted buns.
Serve the pickles on the side with sliced onion and ketchup.
