Choose your substitute based on dish type: canned salmon or chickpeas + seaweed for cold salads, jackfruit for vegan flaky texture, hearts of palm for texture only, smoked mackerel for cooked dishes.
Prep the substitute: drain canned fish, press and crumble tofu, mash chickpeas with seaweed, shred or flake as needed.
Apply the substitution at a 1:1 volume ratio, adjusting seasoning with soy sauce, lemon, seaweed flakes, or miso to boost umami and saltiness.
Incorporate the substitute into your recipe, mixing thoroughly to combine flavors and textures.
Taste and adjust seasoning or texture if needed before serving or cooking further.
