Directions
Prepare
Rub and wipe the trout very dry.
Braise and serve
In a fish kettle, bring water to a boil and add ⅓ cup of vinegar and 2 tablespoons of salt.
Add the trout and a piece of horseradish to the boiling water.
Boil slowly for 20 to 30 minutes, ensuring the skin does not break.
Serve on a napkin with anchovy sauce or plain melted butter.

What each ingredient does
- Vinegar
- Adds acidity to the poaching liquid, sharpening the flavour of the fish.
- Trout
- The main protein, which firms and turns opaque as it cooks in the liquid.
The step that matters
Boil slowly and keep the skin intact. A gentle simmer cooks the fish evenly, while a hard boil can break the skin and cause the flesh to fall apart.
