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 the green body of the soup.
Butter
Carries the onion's flavour and adds richness to the base.
Flour
Thickens the stock into a smooth, body-rich soup as it cooks.
Onion
Softens and sweetens in butter, building an aromatic base.
Milk and cream
Add creaminess and softness to the finished soup.

The step that matters

Cooking the flour into the base. Flour must be cooked long enough to lose its raw, pasty taste and to thicken evenly. Adding it to hot liquid without stirring can leave lumps, so keep stirring while the mixture cooks.

Swap the onion

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

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

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