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

What each ingredient does

Anchovies
Dissolved into the sauce to give a salty, savoury depth of flavour.
Veal broth
Forms the liquid base of the sauce, carrying the other flavours.
Fresh butter
Adds richness and a smooth, glossy texture as it melts into the sauce.
Capers
Add a sharp, briny acidity that cuts through the richness of the butter.
Shallot vinegar
Adds acidity and a mild shallot aroma that brightens the sauce.

The step that matters

Add the butter and heat until boiling. Butter is an emulsion of fat and water that can separate if overheated. Bringing the sauce to a boil gently and then thickening it keeps it smooth rather than oily.

Swap the nutmeg

How well each one fits the dish's main ingredients (veal, sauce, shallot, vinegar, butter, pepper, capers):
