To Boil Fish
Ingredients
Directions
Prepare
Clean and rinse the fish.
Wrap the fish in a cloth and place it in a kettle with cold water.
Boil
Add ½ cup of coarse sea salt and boil slowly, ensuring the water always covers the fish.
Remove any scum that rises to the surface.
Add 1 tablespoon of vinegar when the fish is nearly done.
The fish is done when the flesh separates easily from the backbone with a thin knife.
Be careful not to overcook the fish.
Serve
Drain the fish on a sieve, keeping it hot.
Carefully place the fish on a platter to avoid breaking it.
Serve with drawn butter.

What each ingredient does
- Whole fish
- Forms the main body of the dish, cooked gently in simmering water until flaky.
- Vinegar
- Added near the end to add a slight sharpness that brightens the mild fish.
The step that matters
Avoid overcooking the fish. Fish proteins tighten and dry out when overheated, so the flesh turns tough and stringy. Gentle, slow boiling and checking for easy separation from the backbone keeps it moist and tender.
