Why it works: Corn and asparagus share more aroma than cooks usually use. They rank in the top 7% of all ingredient pairs, and cooks put them together in 84 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main vegetable flavour and body of the soup.
- Corn starch
- Thickens the soup as its granules swell when heated in liquid.
The step that matters
Stir in the corn starch and cook for 10 more minutes. Starch granules thicken the soup only when heated in liquid. Stirring as it goes in prevents lumps, and cooking long enough lets the starch fully thicken and loses its raw, chalky taste.

Fit is the average pairing score against corn, pepper. Candidates are from the same food group and used in at least 100 recipes.
