For Boiling Fish
Ingredients
Directions
Prepare
Sprinkle the fish with coarse sea salt and let it sit overnight.
In a kettle, bring two-thirds full of water to a boil.
Add vinegar and salt to the boiling water.
Place the fish on a drainer or roll it in a cloth, then submerge it in the boiling water.
Boil
For a four-pound fish, boil rapidly for 30 minutes.
For salmon, use tepid water and skim thoroughly, boiling for the same time.
For small fresh-water fish, use cold water; they are cooked as soon as they boil.

What each ingredient does
- Fish
- Provides the main protein that firms and turns opaque as it cooks in the water.
- Coarse sea salt
- Seasons the fish during its overnight rest and seasons the boiling water.
- Vinegar
- Adds a mild acidity to the boiling water that brightens the fish's flavour.
The step that matters
Keep the water at a rapid boil when the fish goes in. Dropping the fish into water that is not boiling vigorously lowers the water temperature and slows cooking, so the fish can cook unevenly and absorb water. A rapid boil helps the fish cook through quickly and firm up evenly.
