The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Butter
Enriches the sauce and carries flavour as the base of the roux.
Flour
Thickens the liquid into a smooth cream when cooked with the butter.
Milk
Forms the creamy body of the soup as it thickens with the roux.
Asparagus cooking water
Adds asparagus flavour and liquid to thin the cream to the desired consistency.

The step that matters

Adding the cold milk to the roux. Cold milk added gradually and stirred constantly blends smoothly into the hot roux. Dumping it in at once or stopping stirring lets starch clump, leaving lumps instead of a smooth, evenly thickened cream.

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.
