Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Pomfret Fillets with Poulette Sauce
Ingredients
Directions
Prepare the fillets
Divide the pomfrets into fillets and season one side with onion, parsley, and mushroom trimmings. Roll up the fillets to enclose the seasoning.
Poach and make the sauce
Simmer the fillets gently in court bouillon or broth made from their bones, stock, Chablis, and vinegar until cooked.
Remove the fillets and strain the broth.
Thicken the broth in a bain‑marie with flour and butter, then add quartered mushrooms, white pepper, and salt.
Off the heat, stir in the strained yolks of the eggs.
Serve
Pour the sauce over the hot fillets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pomfret
- Provides the delicate white fish flesh that is the main component of the dish.
- Flour
- Thickens the broth into a smooth, coating sauce when cooked with butter.
- Butter
- Enriches the sauce with fat, adding richness and smooth texture.
- Egg yolks
- Thicken and enrich the sauce when stirred in off the heat, giving it a silky body.
- Button mushrooms
- Add earthy flavor and texture to the sauce.
The step that matters
Adding the egg yolks off the heat. Egg yolks thicken through gentle heat. If the sauce is too hot when they are stirred in, the yolks can scramble and turn grainy, so the sauce must be removed from the heat first.
Swap the white pepper
How well each one fits the dish's main ingredients (onion, parsley, mushroom, vinegar, flour, butter, egg):
- Capersfits better
- Thymefits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against onion, parsley, mushroom, vinegar, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
