The recipe

Time4 to 5 minutes

Ingredients

Contains: milk, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Make the sauce

  1. In a sauté pan, large enough to hold the catfish fillets in a single layer, melt 4 ounces of the butter over moderately high heat.

  2. When the butter foams up, then begins to die down, toss in the morels, scallions, and shallots.

  3. Cook for about 4 minutes or until the scallions begin to soften.

  4. Add tomato, vermouth, and fish stock; stew gently for about 5 minutes.

  5. Pour the mixture into a bowl and set aside.

Cook and serve

  1. Return the skillet to the stove over moderately high heat and add the last tablespoon of butter.

  2. While it melts, season the fillets with salt and pepper and place them in the skillet.

  3. Cook for 1 minute on each side.

  4. Pour the morel and scallion mixture over the catfish fillets and gently simmer for 4 to 5 minutes, or until the fish is just cooked through.

  5. If the sauce begins to separate, add more vermouth or water, one tablespoon at a time.

  6. When finished, stir in the chervil and transfer to a warm serving platter.

  7. Serve immediately.

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

What each ingredient does

Unsalted butter
Carries flavor and gives the sauce a rich, silky body.
Morel mushrooms
Add an earthy, meaty flavor and a pleasant chew to the sauce.
White vermouth
Adds acidity and aromatic depth as it stews with the other ingredients.
Fresh tomato
Adds acidity and moisture that loosen and brighten the sauce.
Shallots
Provide a mild onion sweetness that deepens as they soften in butter.

The step that matters

Simmering the fish in the sauce. Simmer only until the fish is just cooked through, because overcooked fish proteins tighten and turn dry. A butter-based sauce can also separate if it boils hard, which is why the recipe suggests adding vermouth or water when it starts to split.

Flavor stand-ins for the chervil

How well each one fits the dish's main ingredients (butter, mushroom, onion, shallot, tomato, vermouth, fish):

  1. Thymebetter flavor fit
  2. Garlicbetter flavor fit
  3. Parsleybetter flavor fit
  4. Chervilthe original

Fit is the average pairing score against butter, mushroom, onion, shallot, tomato, vermouth, fish. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
