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 ↓
Asparagus Soup
Ingredients
Directions
Prepare the asparagus
Cut the tips from the asparagus, about ½ inch long.
Cook the remaining asparagus in boiling water until tender.
Rub the cooked asparagus through a coarse sieve and season with salt.
Make the soup
Heat the stock until boiling, then add the butter and flour mixed together with the asparagus pulp.
Boil slowly for 15 minutes.
Stir in the cream and pour the soup into a tureen over the cooked asparagus tips.

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 the pulp that thickens the soup body.
- Butter
- Adds richness and carries flavour through the soup.
- Flour
- Thickens the soup by swelling in the hot stock with the butter.
- Veal stock or milk
- Forms the liquid base of the soup.
- Cream
- Adds richness and a smoother, silkier mouthfeel at the end.
The step that matters
Adding the butter and flour to the boiling stock. Flour clumps if it hits hot liquid unmixed. Mixing it with butter and asparagus pulp first and then stirring it into boiling stock helps it disperse evenly and thicken smoothly.
Swap the asparagus

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