Boiled Eels

Ingredients

Directions

Prepare the poaching liquid

  1. Pare the lemon, removing the white inner rind, slice it, and remove the seeds.

  2. Combine the lemon, white peppercorns, coarse sea salt, and parsley in a pot with 3 pints of cold water.

  2. Lift the eels into a hot dish.

Make the sauce and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eels
Are the main protein; gentle simmering cooks them through while keeping the flesh tender.
Clotted cream
Adds richness and body to the sauce, giving it a smooth, thick texture.
Flour
Thickens the butter and cream into a stable sauce that coats the eels.
Butter
Adds fat and flavour to the sauce and helps the flour blend smoothly.
Lemon juice
Adds acidity that brightens the rich cream sauce and balances its richness.

The step that matters

Simmer the eels gently. Boiling eels hard makes the delicate flesh break apart and turn tough. A gentle simmer cooks the fish evenly while keeping it moist and intact.
