Lamprey Stewed

Ingredients

Directions

Prepare the fish

  1. Wash the lamprey thoroughly in salted warm water.

  2. Remove the head, tail, and fins.

  3. Cut the fish into 2-inch lengths.

  4. Bring the stock or water to a boil.

  5. Add the fish, bay leaf, and seasoning to the boiling liquid. Simmer gently for about 30 minutes.

Make the sauce

  1. In another pan, melt the butter.

  2. Lightly fry the onions. Add the flour to the onions and fry slowly until well browned.

  3. After the fish has stewed for 30 minutes, pour the cooking liquid over the butter and flour mixture. Stir until boiling.

  4. Add the mushrooms and lemon juice to the sauce.

Finish and serve

  1. Place the fish in the sauce. Simmer gently for an additional 30 minutes.

  2. Serve with the sauce strained over the fish and garnish with lemon slices.

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

What each ingredient does

Lamprey
Is the main protein, becoming tender and flaky as it simmers in the stew.
Flour
Thickens the butter and onion mixture into a smooth sauce when cooked with the liquid.
Butter
Carries the onions and flour and adds richness and browning to the sauce base.
Onions
Provide sweetness and savoury depth as they soften and brown in the butter.
Lemon juice
Adds acidity that brightens the rich sauce and balances its flavour.

The step that matters

Frying the flour until well browned. Cooking the flour in butter until browned develops a nutty flavour and removes raw starch taste, while stirring prevents lumps. Slow, gentle frying avoids scorching before the sauce is thickened with liquid.

Swap the onion

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