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

What each ingredient does

Asparagus
Provides the main flavour and bulk of the sauce, with its tender stalks blending into the mixture.
Flour
Thickens the melted butter into a smooth, cohesive base for the sauce.
Butter
Adds richness and fat, carrying flavour and giving the sauce a smooth texture.

The step that matters

Whisk the flour into the melted butter. Stirring the flour into the melted butter cooks out its raw taste and keeps it from clumping, which gives a smooth, thickened base.

Swap the asparagus

How well each one fits the dish's main ingredients (flour, butter, pepper):

  1. Shallotfits better
  2. Chivefits better
  3. Capsicumfits better
  4. Asparagusthe original

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