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
- Asparagus stalks
- Provides the main flavour and, once puréed, the body of the soup.
- Milk
- Adds creaminess and a mild sweetness that softens the vegetal taste.
- Butter and flour
- Together form a roux that thickens the soup and gives it a smooth texture.
- Cream
- Adds richness and a silkier mouthfeel to the finished soup.
The step that matters
Stirring the butter and flour into the soup. Flour clumps if added raw to hot liquid. Smoothing it with butter first and stirring it in evenly lets the starch disperse and thicken the soup without lumps.
Swap the asparagus
How well each one fits the dish's main ingredients (milk, butter, flour, cream):
- Potatofits better
- Leekfits better
- Arrowrootfits about as well
- Asparagusthe original
Fit is the average pairing score against milk, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
