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

What each ingredient does

Butter
Adds fat and richness, and carries the flavour of the onion.
Flour
Thickens the milk into a smooth, creamy base when cooked briefly with the butter.
Milk
Forms the creamy liquid body of the bouillon once thickened.
Minced clams
Provide the main clam flavour and seafood character of the bouillon.
Onion
Adds savoury sweetness and aroma when sautéed until light brown.

The step that matters

Adding the warmed milk to the roux. Adding the milk gradually while stirring constantly keeps the flour evenly dispersed, so the mixture becomes smooth rather than lumpy as it thickens.

Swap the onion

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

  1. Potatofits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Onionthe original

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