Why it works: Asparagus and flour work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 936 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tips
- Provide the main flavor and body of the soup.
- Flour
- Thickens the strained liquid so the soup becomes creamy.
- Hot milk
- Adds richness and mellows the soup into a smooth cream.
- Whipped cream
- Adds fat and a cool, silky finish at serving.
The step that matters
Whisking in the flour. Flour must be whisked into hot liquid so its starch disperses evenly; added in lumps or to cold liquid it forms clumps that stay in the soup and make it grainy.
Swap the asparagus
How well each one fits the dish's main ingredients (flour, milk, cream):
- Arrowrootfits better
- Potatofits better
- Leekfits better
- Asparagusthe original
Fit is the average pairing score against flour, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
