On Boiling Fish
Ingredients
Directions
Prepare
Rub the fish with vinegar or lemon juice.
Place the fish on the drainer of a fish kettle.
Cover the fish with boiling water.
Boil and test
Add plenty of salt and 2 teaspoons of vinegar to the water.
Boil for 3 to 5 minutes, then reduce heat to simmer.
Skim off any scum that rises.
Test the fish with a skewer; it's done when the flesh parts easily from the bone.

What each ingredient does
- Whole fish
- Forms the main body of the dish, cooked gently in the poaching liquid.
- Vinegar
- Adds a sharp acidity that brightens the mild flavour of the fish.
The step that matters
Keeping the water at a simmer after the initial boil. A hard boil keeps the water churning and can break the fish apart and toughen the flesh. Gentle simmering cooks the fish evenly while keeping it moist and intact.
