Kiawe lump charcoal

The Founder's Smash Burger

20 min · Easy · Makes 4 doubles

A smash burger with actual kiawe smoke in it — the thing a kitchen griddle can never do. Cast iron flat-top on the grate over kiawe lump, chips rolling on the coals, and the pineapple caramelized in the beef tallow right beside the patties. Salt, pepper, meat, fire — the founder's rules — with the islands riding on top.

The griddle is the whole game: 425-450F on the surface, checked with an IR gun on the matte black seasoning (never a shiny oil spot — reflective surfaces read falsely low). Below 400 the meat steams; above 500 the tallow scorches and buries the kiawe.

The Numbers

  • Griddle: 425-450F surface, IR gun
  • Per Side: 90 seconds
  • Time: 20 min
  • Burn: Kiawe lump + chips (gas: foil-wrapped chunk)

Ingredients

  • 1 1/2 lbs 80/20 ground chuck, rolled loose into 8 x 3-oz balls — do not pack them
  • Salt and coarse black pepper, nothing else on the meat
  • 8 thin pineapple slices (about 1/4 inch), patted VERY dry
  • 8 slices American cheese
  • 4 King's Hawaiian hamburger buns
  • Island mayo: 1/2 cup mayonnaise + 2 tsp shoyu + a splash of chili pepper water
  • Chili pepper water (2-3 days ahead): 10-15 Hawaiian chilies (nīoi — Thai bird works), halved + 1 1/2 cups boiling water + 1 Tbsp vinegar + 1 tsp coarse salt
  • A little beef tallow to start — the patties render the rest

Method

  1. Flat-top across the grate over a full chimney of kiawe lump, lid closed, 10-15 minutes to 425-450F on the surface. Gas: foil-wrapped kiawe chunk or split on a lit burner — wait until the smoke is really rolling.
  2. A handful of kiawe chips on the coals, then balls down and smash HARD for 10 seconds each — thin, ragged, lacy edges. Lid stays open from here.
  3. Salt and pepper the smashed side. 90 seconds a side — deep mahogany edges, then scrape-flip with a stiff spatula and take the crust with you. Cheese on every patty after the flip; stack into pairs.
  4. Pineapple rings down in the tallow beside the meat, 1-2 minutes a side until caramelized dark at the edges. Dry fruit caramelizes; wet fruit steams.
  5. Buns cut-side down in the tallow corner — 15-20 seconds only; King's Hawaiian runs sweet and toasts fast. Island mayo both sides, double stack, pineapple ring on top.
  6. Between batches, give the griddle 60-90 seconds to climb back to temp. Rest: zero minutes — smash burgers wait for no one.
