Yield: 4 burgers Prep time: 20 minutes, plus 30 minutes chilling Cook time: 15 minutes Make-ahead: Patty mixture keeps up to 3 days refrigerated, per Delish

Ingredients:

For the shoyu sauce:

• ¼ cup shoyu
• 3 tablespoons packed light brown sugar
• 1½ teaspoons finely grated fresh ginger
• 2 small garlic cloves, minced
• 1 teaspoon toasted sesame oil

For the patties:

• About 1¼ pounds boneless chicken thighs, finely chopped by hand or pulsed briefly in a food processor
• 2–3 tablespoons of the shoyu sauce (measured out before reducing)
• ½ teaspoon black pepper

For the build:

• 4 brioche or potato rolls, toasted
• Shoyu mayo (Japanese mayo whisked with a small amount of reduced glaze)
• 4 grilled pineapple rings
• Quick-pickled red onion
• Shredded cabbage dressed with rice vinegar and sesame oil

Shoyu is a Japanese-style soy sauce brewed from soybeans and wheat. Simply Recipes describes the flavor as "sweet-and-salty, nuanced" softer than Chinese-style soy sauce because the wheat rounds the edges. That softness is what lets it work alongside brown sugar without tipping into cloying.

Locally made Hawaiian shoyu is the standard in Hawai'i. Delish describes it as lighter, less salty, and slightly sweeter than mainland brands. Outside the islands, Aloha brand is the closest widely available equivalent. Simply Recipes notes that Kikkoman works comparably, but it runs saltier; if that's what's in the pantry, taste the mixed sauce before adding it to the patty and pull back by a tablespoon.

The sauce ratio here leans toward the leaner end of what traditional recipes use. The Bittman Project uses equal parts shoyu and brown sugar, one cup each, for a six-serving braise. Simply Recipes uses half a cup shoyu to one-third cup brown sugar for four servings. For a glaze that will concentrate further on the stovetop, starting leaner prevents it from becoming too sweet after reduction.

Whisk the shoyu, brown sugar, ginger, garlic, and sesame oil until the sugar dissolves, about 30 seconds. Measure out 2–3 tablespoons for the patty and reserve the rest for the glaze.

The traditional braising liquid also includes stock or water. The Bittman Project uses one cup of chicken broth; Simply Recipes uses nearly two cups of unsalted stock across the dish. That liquid dilutes the sauce for a long, slow braise. Omit it from the patty seasoning entirely. If the glaze tightens too fast during reduction, a tablespoon of water will loosen it.

Step 1: Prepare the chicken.

Start with boneless chicken thighs, not pre-ground chicken breast. The Bittman Project and Simply Recipes both specify bone-in thighs for the traditional dish, specifically for texture and fat content. The same logic carries into the burger: use the same cut, just deboned. Aim for about 1¼ pounds for four patties.

Chop finely by hand or pulse briefly in a food processor. The goal is a rough, chunky texture, not a paste.

Step 2: Mix and form the patties.

Combine the chopped chicken with the reserved 2–3 tablespoons of shoyu mixture, the teaspoon of sesame oil, and a half-teaspoon of black pepper. Black pepper appears in The Bittman Project's spice list for the traditional preparation. Mix until just combined. Overworking tightens the protein structure and produces a dense, rubbery patty. Form into four rounds roughly three-quarters of an inch thick. Press a shallow indent in the center of each with your thumb to prevent doming during cooking.

Gotcha: Do not marinate the formed patties in additional shoyu mixture overnight. The Bittman Project's overnight marinating instruction applies to whole bone-in thighs going into a long braise. Finely chopped patties are a different animal; extended liquid exposure softens the structure and makes them difficult to handle on the grill. The 2–3 tablespoons mixed in are sufficient seasoning.

Step 3: Chill the patties and reduce the glaze.

Refrigerate the formed patties for at least 30 minutes before grilling. This firms the structure before they hit the heat. If making the mixture ahead, Delish notes it can be stored in an airtight container for up to three days; form and chill the patties the day of cooking.

While the patties chill, reduce the glaze. Pour the reserved shoyu mixture into a small saucepan over medium heat. Simmer, stirring, until thick enough to coat the back of a spoon, about one minute at a low boil, as Simply Recipes describes for the traditional sauce. Both The Bittman Project and Simply Recipes use cornstarch to thicken the sauce in the braised version; for the burger glaze, natural reduction produces a cleaner result. If it tightens too aggressively, add a tablespoon of water and stir to loosen.

Step 4: Grill and glaze.

Cook the patties over medium-high heat for 5–6 minutes per side, until the internal temperature reaches 165°F, the doneness target Simply Recipes uses for the traditional dish. Don't press down on the patties during cooking.

In the final two minutes, brush the reduced glaze onto the top surface, flip once, apply a second coat, and pull off the heat. The surface should look sticky and slightly darkened. If it's charring rather than caramelizing, move to indirect heat immediately.

Lightly toast a brioche or potato roll cut-side down on the grill for about 60 seconds. Stack: bottom bun, shoyu mayo, glazed patty, one grilled pineapple ring, quick-pickled red onion, shredded cabbage slaw, top bun.

Each topping is there for contrast. The glaze runs sweet and rich; pineapple adds caramelized acidity, pickled onion cuts through the fat, and cabbage slaw provides crunch and a clean finish. Without that contrast, the burger becomes one-note by the third bite.

Common problems and fixes:

• Patties falling apart on the grill: Not chilled long enough, or the mixture was overworked. Next time, chill for a full hour and mix more lightly. In the moment, use a thin spatula and flip only once.
• Glaze burning before the patty is cooked through: Heat is too high, or the glaze went on too early. Move to indirect heat for the glaze step and apply with two minutes left, not five.
• Too salty: The sauce was built with standard soy sauce at full quantity. Reduce the shoyu by one tablespoon and add a teaspoon of water to the glaze base. Taste before mixing into the patty.
• Patty tastes flat despite the right ingredients: Sesame oil was omitted, or the ginger was old. Fresh-grated ginger is non-negotiable; the dried version doesn't carry the same sharp aromatic lift that defines the flavor profile.

The four-ingredient formula, shoyu, brown sugar, ginger, garlic, is what Hawaii Monthly describes as the backbone of a landmark local comfort dish. The burger earns its place by treating that flavor seriously rather than using it as a shortcut.

Make the patty mixture up to three days ahead, per Delish. Reduce the glaze the day of. Assemble cold toppings while the grill heats. Once you've made the burger once, the natural next move is adjusting the glaze ratio to taste, or pulling back the brown sugar by a tablespoon if you want something less sweet and sharper on the ginger.

If you want to understand the dish before adapting it further, The Bittman Project's traditional shoyu chicken recipe is worth making first. Cook the original once and every decision in the burger version makes more sense.
