Shoyu-koji Salmon Poké Bowl

Jump to Recipe 👇

The Poké bowl (pronounced poh-KAY) originated in Hawaii with its roots in Polynesian culture. In Hawaiian, poké means to cut or slice and, judging by the multi-coloured offerings strewn across Instagram, it is one of those freestyle dishes where you can cut and slice pretty much whatever you want, however you want.

Preceding social media by some way, the Japanese certainly played their part in the evolution of this dish, introducing the flavours of soy, sesame and vinegar from the late 19th century. The modern poké is the ultimate in health-conscious, eye-pleasing comfort food—a vibrant, colourful bowl that hits every nutritional note. While most Poke relies on a quick splash of soy sauce, we take things a step further by marinating the salmon in shoyu-koji.

As well as the shoyu-koji, the addition of garlic and ginger really gives this dish a kick and adds to the overall moreishness.

This isn’t just about flavour; it’s about transformation. If you have the patience to marinate the salmon overnight, the koji enzymes work their magic, turning the fish buttery and incredibly silky (what we call nettori in Japan). Feel free to pile on the colours and textures to sing alongside that beautiful salmon.

Ingredients
  

The Fish & Marinade

  • 200 g salmon fillet (sashimi-grade)
  • 20 g shoyu-koji (10% of the weight of the salmon)
  • 1 tsp crushed garlic
  • 1 tsp grated ginger

The Bowl

  • 200 g steamed rice (per person or portioned to suit)
  • 1 avocado, diced
  • 1 yellow pepper, sliced
  • ⅛ red cabbage, finely sliced
  • ½ carrot, finely sliced
  • ½ cucumber, diced (remove seeds, use flesh only)
  • ½ red onion, finely sliced
  • 2 radishes, finely sliced
  • 120 g edamame (shelled)
  • 1 tbsp toasted sesame seeds
  • 1-2 spring onions, finely chopped
  • shredded nori seaweed (to garnish)

The Sauce

  • 2 tbsp shoyu-koji
  • 2 tbsp white tahini (sesame paste)
  • 2 tsp white wine vinegar
  • 2 tsp honey
  • 2 tsp lemon juice
  • 2 tsp sesame oil

Instructions
 

  • Prepare the Salmon: Pat the salmon dry with kitchen paper to remove any excess moisture and cut into 1.5cm cubes.
  • Marinate: Place the salmon and the marinade ingredients into a freezer bag, massage lightly to coat evenly, squeeze out the air and seal, then leave in the fridge for about 1 hour.
  • Make the Sauce: Mix the sauce ingredients together and set aside.
  • Prep the Vegetables: Slice the red onion and soak in water for 5 minutes, then drain and pat dry. Prep the remaining veggies in your preferred style.
  • Final Prep: Just before serving, take the salmon out of the fridge and dice the avocado.
  • Build the Bowl: Place the steamed rice in the centre of a bowl, then arrange the marinated salmon on top. Then arrange the rest of the vegetables around the centrepiece.
  • Garnish and Finish: Drizzle the sauce over the dish and then finish by scattering the sesame seeds, spring onions, and nori over the top.

Notes

Texture & Enzyme Action: Leaving the fish to marinate longer for half a day to overnight allows the enzymes to work their magic, resulting in a richer and more melt-in-the-mouth texture. The word in Japanese is nettori (ねっとり).
