What each ingredient does
- Conger eel
- Is the main protein, cooked gently in simmering liquid until tender and flaky.
- Vinegar
- Adds acidity to the cooking liquid, brightening the mild flavour of the fish.
- Butter or dripping
- Adds richness and fat, giving the eel a smooth, savoury finish when served melted.
The step that matters
Simmering gently for 30 minutes. A rolling boil can break up the delicate flesh of the eel and make it tough or ragged. Keeping the liquid at a gentle simmer cooks the fish evenly while it stays intact.
