What each ingredient does
- Eel
- Main protein; its flesh firms and turns opaque as it cooks.
- Butter
- Adds richness and a smooth, savoury fat when served melted over the eel.
The step that matters
Boil until just cooked. Eel flesh is delicate. Boiling it too long squeezes out moisture and toughens the protein, so it turns dry and rubbery. Stop as soon as the flesh is opaque and flakes easily.
