Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cream of Asparagus Soup
Ingredients
Directions
Prepare
Wash and boil the asparagus in salted water until tender.
Cut the tips from 1 bunch and set aside.
Press the remaining asparagus through a colander into the soup stock.
Make the soup
Heat the butter in a pot, add the flour, and stir until smooth.
Gradually add the hot cream or milk, stirring until thickened.
Stir in the asparagus stock and season with salt and pepper.
Serve
Pour into a tureen, add the asparagus tips and additional butter, and serve immediately.

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
- Provides the main flavour and, when pressed through a colander, body to the soup.
- Flour
- Thickens the butter and cream mixture into a smooth base for the soup.
- Butter
- Adds richness and carries the flour so it cooks smooth before the liquid goes in.
- Hot cream or rich milk
- Adds richness and a creamy texture as it thickens the soup.
- Soup stock
- Forms the liquid base that carries the asparagus flavour.
The step that matters
Add the hot cream or milk gradually. Adding the liquid slowly while stirring keeps the flour smooth and lump-free, so the soup thickens evenly instead of forming clumps.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, flour, cream, pepper):
- Spinachfits better
- Leekfits better
- Potatofits better
- Asparagusthe original
Fit is the average pairing score against butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
