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

What each ingredient does

Veal broth
Forms the liquid base of the soup and carries its savory flavor.
Asparagus
Provides the main vegetable flavor and, once pureed, body to the soup.
Flour
Thickens the soup by swelling in hot liquid as its starch sets.
Butter
Adds richness and smooth mouthfeel to the thickened soup.
Milk or cream
Adds creaminess and softens the flavor of the soup.

The step that matters

Stirring the flour and butter into the soup. Flour mixed smoothly with butter, then whisked into hot liquid, thickens evenly. If it is added as lumps or not fully blended, it clumps and the soup stays uneven in texture.

Swap the onion

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

  1. Leekfits better
  2. Chivefits better
  3. Potatofits better
  4. Onionthe original

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