Lombardy Eels, Soused or Marinaded

Ingredients

Directions

Prepare the eels

  1. Clean the eels thoroughly with sand and rinse in several waters.

  2. Cut the eels into 4 to 5‑inch pieces.

  3. Fry the pieces in oil or lard until cooked.

Make the souse

  1. In a separate pot, boil equal parts vinegar and water with salt, bay leaves, rosemary, ginger, capsicum, and any other spices to taste.

  2. Adjust the marination with boiling water if it is too salty or acidic.

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

What each ingredient does

Vinegar
Provides the sharp acidity that defines the souse and helps preserve the marinated eels.
Oil or lard
Conducts heat for frying and adds fat that browns the eel pieces.
Bay leaves
Adds a subtle herbal aroma to the marinade.
Rosemary
Adds a resinous, piney aroma to the marinade.
Ginger
Adds a warm, pungent aroma and flavor to the marinade.

The step that matters

Adjust the marination with boiling water. Vinegar and salt are concentrated in the boiled souse, so the balance can overpower the eels. Diluting with boiling water lowers the salt and acidity, keeping the flavor pleasantly balanced.

Swap the ginger

How well each one fits the dish's main ingredients (vinegar, rosemary, capsicum):

  1. Basilfits better
  2. Thymefits better
  3. Oreganofits better
  4. Gingerthe original

Fit is the average pairing score against vinegar, rosemary, capsicum. Candidates are from the same food group and used in at least 100 recipes.
