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

What each ingredient does

Butter
Adds richness and a smooth, rounded flavor to the sauce.
Egg yolks
Enriches and thickens the sauce, giving it a creamy body.
Cornstarch
Thickens the liquid so the sauce holds together rather than running thin.
Milk
Forms the liquid base of the sauce and adds creaminess.
Asparagus
Provides the main vegetable flavor and tender texture in the dish.

The step that matters

Adding the milk and asparagus water gradually. Egg yolks can curdle and cornstarch can clump if liquid goes in too fast or the heat is too high. Adding the liquid slowly while stirring keeps the sauce smooth and evenly thickened.

Swap the white pepper

How well each one fits the dish's main ingredients (asparagus, egg, butter, milk, celery):

  1. Tarragonfits better
  2. Parsleyfits better
  3. Nutmegfits better
  4. White pepperthe original

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