  • 7 oz of beef mince (⅔ brisket and ⅓ chuck steak) split into 3.5 oz patties
  • Kosher salt for seasoning
  • 1 bun per burger (I used brioche)
  • 2 pieces sliced American cheese per burger
  • Pickles (I prefer bread and butter flavored pickles)
  • Mustard
  • Kewpie mayonnaise (Japanese Mayonnaise)

For the Spicy Ketchup:

  • 2 cups passata sauce (tomato puree)
  • 2 tbsp garlic powder
  • 2 tbsp onion powder
  • 1 tbsp raw sugar
  • 2 tbsp Tabasco sauce
  • 1 good pinch of salt flakes
  • 1 pinch of finely ground black pepper


  • Roll brisket and chuck ground meat into 3.5 oz balls (2 per burger).
  • Heat grill to a hot temp.
  • Combine all spicy ketchup ingredients in a pan and heat over a low heat for a couple of minutes until the sugars are all dissolved, then allow to cool and transfer to a sauce bottle.
  • Oil grill and place balled up mince (2 per burger) on hotplate, you should hear a sizzle as the meat touches the grill.
  • Season balls with a good sprinkle of kosher salt.
  • Flatten mince with burger smasher, using a baking paper to stop the smasher sticking to the patties.
  • Once fluid is visible on to of burger patties, it’s time to turn them over.
  • Place a piece of American cheese on each patty and place burger buns on grill to brown.
  • Once cheese is melted, take buns off the heat.
  • Apply Kewpie mayonnaise to bottom buns.
  • Add two burger patties to bottom bun.
  • Apply mustard, ketchup and pickles to the top.
  • Add top part of bun.
  • Eat and enjoy!
