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

What each ingredient does

Young asparagus
Forms the main body of the dish and gives its tender, fresh texture.
Butter
Adds fat and richness, carrying the flavour of the herbs during frying.
Flour
Dusted over the mixture to thicken the liquid into a sauce.
Boiling water
Moistens the floured mixture so it can cook down into a sauce.
2 egg yolks
Thickens the sauce and gives it a rich, smooth body when gently heated.
Cream or melted butter
Adds fat and smoothness to the egg yolks, enriching the sauce.

The step that matters

Thicken the sauce with egg yolks. Egg yolks set when heated, so if the sauce boils after they are added it can scramble and turn grainy. Add them off the heat or over very gentle heat, stirring constantly.

Swap the mint

How well each one fits the dish's main ingredients (asparagus, butter, parsley, onion, flour, sugar, egg):

  1. Capersfits better
  2. Tarragonfits better
  3. Nutmegfits better
  4. Mintthe original

Fit is the average pairing score against asparagus, butter, parsley, onion, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
