Lean double smash burger with special sauce

Set a bowl on a scale and combine 70 grams mayo, 80 grams ketchup, a splash of pickle liquid and a teaspoon each of smoked paprika, onion powder and black pepper; mix.

Thinly slice the lettuce, the tomato (with a sprinkle of salt) and the white onion.

Divide the beef into two 85 gram balls and sprinkle with salt and MSG.

On a ripping hot surface, press each ball down and cook 45 to 60 seconds before flipping; the low fat content means little browned crust.

Lay a slice of American cheese on each patty and stack them.

Spread 7 grams of sauce on the top and bottom bun, then the salted tomato, the lettuce, then the burger; In-N-Out puts the onion between the patties.
