  2. Add the anchovies, capers, chopped leeks, nutmeg, a little vinegar, and water to the melted butter.

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, cooked gently in the covered pan until it turns flaky and opaque.
Butter
Forms the rich base of the sauce, adding fat and a smooth, velvety texture.
Flour
Thickens the melted butter into a sauce as it is stirred and heated.
White wine
Adds acidity and aroma to the poaching liquid, flavouring the fish as it simmers.
Anchovies
Dissolve into the butter, adding savoury depth to the sauce.
Capers
Add a sharp, briny acidity that cuts through the richness of the butter sauce.

The step that matters

Stirring the sauce while the flour goes in. Flour added to hot butter clumps unless it is stirred constantly, so the sauce can become lumpy instead of smooth and thickened.

Flavor stand-ins for the leek

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