South Wales Salmon

Ingredients

Directions

Prepare the salmon

  1. Make incisions between the head and tail of the salmon, 2 inches wide and 1 inch deep.

  2. Soak the salmon in cold water for 1 hour.

  3. Place the salmon in a fish kettle with enough cold water to cover it.

  4. Add ½ cup of coarse sea salt and ⅓ cup of vinegar to the water.

Poach and cool

  1. Heat the water until it is scalding hot, then remove from heat.

  2. Pour the hot water into a pan and let the salmon cool in a strainer over the pan until the next day.

  3. Reheat the salmon in the same water until warmed through, ensuring it does not boil.

Serve leftovers

  1. If there is leftover salmon, fry it in batter after sprinkling with salt and optionally adding Granville fish sauce.

What each ingredient does

Coarse sea salt
Seasons the salmon and firms its flesh during the soak and poach.
Vinegar
Adds a mild acidity that brightens the flavour of the fish.

The step that matters

Reheating without boiling. Keeping the water just below a boil warms the salmon gently. Boiling toughens the proteins in the flesh, making it dry and firm, so the fish stays moist and tender.
