What each ingredient does
- Trout
- Is the main protein, cooked gently in the poaching liquid until it turns flaky and opaque.
- Onion
- Adds savory sweetness and aromatic depth to the poaching liquid as it simmers.
- Bay leaves
- Contribute a subtle herbal aroma to the poaching liquid.
- Whole allspice
- Adds warm, aromatic spice notes to the poaching liquid.
The step that matters
Bring to a boil, then reduce heat and simmer. Gentle simmering cooks the fish evenly and keeps the flesh tender and moist. A hard boil can toughen the proteins and break the fish apart.
