Why it works: Asparagus and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,968 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Prepare the asparagus
Cut off the tips of the asparagus, about an inch long.
Simmer the tips in water with salt until tender.
Make the soup

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, through the stalks, the body of the soup.
- Flour
- Thickens the strained liquid by swelling with heat, giving the soup a smooth, body-rich texture.
- Sweet cream
- Adds richness and fat, giving the soup a softer, silkier mouthfeel.
The step that matters
Thickening the strained liquid with flour. Flour must be boiled for the full two minutes so its starch swells and cooks out. Otherwise the soup can taste raw and floury and stay thin.
Swap the asparagus
How well each one fits the dish's main ingredients (flour, cream, pepper):
- Spinachfits better
- Arrowrootfits better
- Parsnipfits better
- Asparagusthe original
Fit is the average pairing score against flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
