Miso-Glazed Ember-Roasted Salmon

There are few flavor combinations as deeply satisfying as the sweet, fermented richness of white miso meeting the smoky, charred edges of live-fire cooking. This recipe bridges Japanese culinary tradition with the raw, elemental technique of ember roasting — the result is a centerpiece dish that's as visually dramatic as it is delicious.

What You'll Need

Ingredients (Serves 4)

  • 1 whole side of salmon (approximately 1.2–1.5 kg), skin on
  • 3 tablespoons white (shiro) miso paste
  • 2 tablespoons mirin
  • 1 tablespoon sake (or dry sherry)
  • 1 tablespoon brown sugar
  • 1 teaspoon toasted sesame oil
  • 2 cloves garlic, finely grated
  • 1 teaspoon fresh ginger, finely grated
  • Sliced spring onions and toasted sesame seeds to garnish

Preparing the Miso Glaze

Whisk together the miso paste, mirin, sake, brown sugar, sesame oil, garlic, and ginger in a small bowl until completely smooth. The glaze should have the consistency of thick honey. Marinate the salmon skin-side down for at least 2 hours, or ideally overnight in the refrigerator — this allows the miso's enzymes to gently cure the fish and deepen the flavor.

Setting Up Your Fire

Ember roasting requires a well-established fire with a thick bed of glowing coals — not open flame. Build your fire 45–60 minutes ahead of cooking using hardwood charcoal or wood chunks. You're aiming for:

  1. A deep bed of white-grey ash-covered coals
  2. An indirect heat zone where the salmon will cook gently
  3. A direct, high-heat zone for final caramelization of the glaze

If you're using a kettle grill or offset smoker, bank your coals to one side. The indirect zone should hold around 180–200°C (350–390°F).

Cooking the Salmon

Place the salmon skin-side down on a cedar plank or directly on an oiled grill grate over indirect heat. Close the lid and cook for 12–15 minutes depending on thickness. During the final 3 minutes, move the salmon over direct heat — watch as the miso glaze bubbles and caramelizes into a deep mahogany crust. This is where the magic happens.

The salmon is done when it flakes easily with a fork at its thickest point but retains a slightly translucent, silky center (internal temperature of around 52°C / 125°F for medium doneness).

Serving Suggestions

Slide the salmon directly onto a serving board. Scatter generously with sliced spring onions, toasted sesame seeds, and a few drops of extra sesame oil. Serve alongside:

  • Steamed jasmine or sushi rice
  • Pickled cucumber ribbons
  • Grilled bok choy finished with soy and chilli

Tips for Success

The miso glaze can burn quickly over direct flame due to its sugar content — never rush the caramelization phase. Keep a spray bottle of water nearby to tame flare-ups. If using a plank, soak it in cold water for at least 30 minutes before cooking to prevent it from igniting.

This recipe rewards patience. The combination of slow indirect heat followed by a fierce, brief caramelization is exactly what makes ember-roasted fish so extraordinary.
