Why it works: Turbot and leek work together. They rank in the top 8% of all ingredient pairs, and 12 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
The recipe
Ingredients
Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Poach the fish
Place the fish on a bed of sliced onion and herbs.
Pour equal parts white wine and vinegar over the fish to cover it.
Sprinkle with grey salt and coarse pepper.
Cook the fish over moderate heat until done, then remove from heat but leave in the saucepan.
Make the sauce
In another saucepan, melt the butter and add anchovies, capers, leeks, pepper, salt, nutmeg, flour, vinegar, and water.
Cook these ingredients over heat, then warm the fish again.
Serve
Serve the fish with some sauce poured over it and horseradish on the side.
Serve the remaining sauce in a separate dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turbot
- Is the main fish that is cooked gently until flaky and done.
- Butter
- Melted to form the rich base of the sauce, adding fat and smooth body.
- Anchovies
- Dissolve into the warm butter to add savory depth to the sauce.
- Capers
- Add sharp, briny acidity that cuts through the richness of the butter.
- Flour
- Thickens the butter and sauce ingredients so they cling to the fish.
- White wine
- Flavors and moistens the fish as it poaches with the vinegar.
The step that matters
Cook the fish over moderate heat until done. Fish proteins set and turn opaque at moderate heat, and overcooking makes the flesh dry and firm. Removing it from heat while it stays in the hot liquid lets it finish gently.

Fit is the average pairing score against turbot, onion, leek, white wine, vinegar, pepper, butter. 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).
