Bladderwrack flakes will be used mainly as a seasoning. Its salty taste will reduce the need for salt in the recipe and round the flavour by adding a ‘seafood’ flavour to the dish. Although it is not necessary to re-hydrate Bladderwrack, rinsing it with water will reduce saltiness and preserve the overall moisture level in the recipe.

  • Eaten on its own, it possesses a slightly salty taste. Boiled or sautéed, it evokes a savoury fish dish.
