Kiawe lump charcoal — 10 lb bag, for a hard sear on ahi tuna

Poke-House Seared Ahi

10 min · Easy · Serves 2

Every good fish counter in Hawaii sells seared ahi with a cold rare center, and the secret is violence: the hottest fire you can build, the shortest cook you can stand. A handful of kiawe chips thrown on right before the fish is the poke-house move.

The fish decides this dish before you light anything. You want a loin you would eat raw, because you essentially are — "sushi-grade" is a marketing term with no legal definition in the United States, so what you are really looking for is a fishmonger who can tell you when it came in and who sells enough of it to turn stock over fast. Deep translucent red, firm, no browning at the edges, and it should smell like nothing at all.

Dry the surface completely before it touches the grate — a wet loin steams and goes grey a quarter-inch deep instead of searing. Work by the clock, not by temperature: 60 to 90 seconds a side. By the time a probe reads anything meaningful, the center you were protecting is already gone.

The Numbers

  • Fire: as hot as the rig will go
  • Sear: 60-90 seconds per side, no more
  • Inside: cold and raw — that is the point
  • Burn: kiawe lump, screaming hot

Ingredients

  • 2 ahi steaks, 1.5 inches thick, sashimi grade
  • 1 Tbsp neutral oil
  • Coarse salt and pepper
  • Shoyu, sliced green onion, and toasted sesame, to serve

Method

  1. Get the fire screaming — flames licking the grate. Throw a handful of kiawe chips on 60 seconds before the fish.
  2. Oil and season the steaks.
  3. Sear 60–90 seconds per side. The center stays cold and red — that's the point.
  4. Slice immediately, against the grain, half-inch thick.
  5. Shoyu, green onion, sesame. Serve over rice or eat standing at the cutting board like everyone actually does.

On Your Rig

Same recipe, different fire. You need maximum heat and nothing else. Whichever of your rigs gets hottest fastest is the right one.
