A smash burger is built on one idea: a cold ball of fatty beef pressed flat into a very hot pan, so as much of it as possible touches the metal and turns into crust. This recipe keeps everything else simple so that crust stays the point.
The beef should be at least 20 per cent fat and straight from the fridge; cold meat holds together when you smash it and fat is what browns. Press hard in the first minute and do not move the patty until a dark crust has formed. The sauce is a quick mix of ketchup, mayonnaise, sweet relish, vinegar, a pinch of sugar and garlic, close to the special sauces of the chains that made this style famous. Toast the buttered buns in the same pan, add Cheddar or Colby, raw red onion and serve straight away.

Recipe

  1. 1
    In a small bowl, stir together the ketchup, mayonnaise, pickle relish, vinegar, sugar and garlic. Season with salt and pepper, cover and set aside: this is the special sauce.
  2. 2
    Divide the beef into 4 equal pieces, roll each into a ball and chill until you cook. Butter the cut sides of the buns.
  3. 3
    Heat a large cast iron or nonstick skillet over medium-high heat, with a little vegetable oil if you are worried about sticking.
  4. 4
    Put two balls in the pan and smash them flat with the bottom of a small saucepan or a spatula. Hold them down for about 1 minute, until they sear, then season with salt and pepper. Cook until a deep crust forms and flip.
  5. 5
    When the second side is nearly done, add a slice of cheese. Push the patties to one side and toast the buns in the pan, buttered side down. Keep cooking the burgers for about 5 minutes, until the cheese melts, the centre is no longer pink and a thermometer reads at least 160 degrees F (70 degrees C).
  6. 6
    Move the buns to a plate, set a patty on each bottom bun and spread the toasted side of the top buns with special sauce.
  7. 7
    Scatter a few onions over each patty and close with the top bun.
