Lamprey, a LA Foley

Ingredients

Directions

Prepare the lampreys

  1. Shape each lamprey into a circle and tie with string.

  2. Stew the lampreys in claret with vegetables until cooked.

Make the sauce

  1. Reduce two-thirds of the cooking liquid with an equal amount of brown sauce and essence of mushrooms.

  2. Once reduced, mix in crayfish butter, nutmeg, lemon juice, and cayenne.

  3. Pass the sauce through a fine sieve into a bain‑marie with crayfish tails and button mushrooms.

Serve

  1. Drain the lampreys and place them in a dish, one on top of the other.

  2. Sauce the lampreys with the prepared ragout and garnish with glazed croutons and fried small fillets of perch.

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

What each ingredient does

Lampreys
Form the main body of the dish, cooked tender in the claret.
Claret
Its liquid cooks the lampreys and, reduced, flavours the sauce.
Brown sauce
Adds body and savoury depth to the reduced cooking liquid.
Crayfish butter
Adds richness and fat, giving the sauce a smooth, rounded texture.
Button mushrooms
Add earthy flavour and a tender bite to the ragout.

The step that matters

Reducing the cooking liquid. Reducing concentrates flavour and thickens the liquid into a sauce. Reduce too little and the sauce stays thin and weak; too far and it turns salty and syrupy.

Swap the nutmeg

How well each one fits the dish's main ingredients (sauce, mushroom, crayfish, butter, lemon, pepper):

  1. Parsleyfits better
  2. Thymefits better
  3. Tarragonfits better
  4. Nutmegthe original

Fit is the average pairing score against sauce, mushroom, crayfish, butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
