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, once blended, the body of the soup.
Butter
Adds fat and richness, and carries flavour through the roux.
Flour
Thickens the soup by forming a roux with the melted butter.
Milk
Adds liquid and creaminess, turning the thickened base into a smooth soup.

The step that matters

Gradually add milk to the roux. Adding liquid slowly while stirring lets the starch granules separate and hydrate evenly, which prevents lumps and keeps the sauce smooth.

Swap the asparagus

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

  1. Potatofits better
  2. Capsicumfits better
  3. Chivefits about as well
  4. Asparagusthe original

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