The flavor team

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Butter and flour
Form a roux that thickens the milk into a smooth, body-rich base.
Milk
Forms the creamy base of the soup and thickens with the roux.
Asparagus
Provides the main vegetable flavor and, from the stalks, body to the stock.
Chicken stock
Carries the asparagus flavor and forms the liquid base of the soup.
Cream
Adds richness and a silkier mouthfeel at the end.

The step that matters

Gradually stir in the milk and cook until thickened. Adding milk all at once to a flour-butter paste can leave lumps. Adding it gradually while stirring keeps the starch evenly dispersed, so the base thickens smoothly.

Swap the asparagus

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

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

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