What each ingredient does
- Eels
- Provide the main protein, which becomes tender and firm after gentle simmering.
- Butter
- Adds richness and moisture, coating the cooked eels with a smooth fat.
- Parsley
- Contributes fresh, herbal aroma that brightens the rich butter and fish.
The step that matters
Simmer until tender. Eels need gentle simmering rather than a hard boil, because strong bubbling can break the flesh apart and make it tough. Keeping the water just below a boil cooks the fish evenly while it stays intact.
