Salmon, to Boil

Ingredients

Directions

Prepare the poaching liquid

  1. Fill a pot with lukewarm water to cover the fish.

  2. Add ½ cup of coarse sea salt and ¼ cup of vinegar to the water.

  3. Bring the water to a gentle boil, skimming off any scum that rises.

Cook and serve

  1. Cook the salmon for 30 to 60 minutes, depending on its thickness.

  2. Check for doneness when the eyes start to bulge and the fins pull out easily.

  3. Let the fish rest on a drainer for a minute before serving.

What each ingredient does

Salmon
Is the main protein, cooked gently in the liquid until it turns opaque and flakes.
Vinegar
Adds a little acidity that brightens the flavour of the poaching liquid.

The step that matters

Keeping the water at a gentle boil. A rolling boil agitates the delicate proteins and can break the fish apart and toughen its texture. A gentle simmer cooks it evenly and keeps the flesh moist and tender.
