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
Open the can of asparagus and rinse thoroughly in cold water.
Drain, cut off the points, and place the stalks in a saucepan with the stock.
Simmer until very tender, then rub through a fine sieve.
Make the soup
Return to the fire, add butter and flour mixed into a paste, and stir constantly until slightly thickened.
Season to taste and simmer for five minutes.
Add hot cream and the asparagus points, then stir in whipped cream and remove from heat.

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 body of the soup once puréed and sieved.
- Butter
- Adds richness and fat, and helps carry flavour through the soup.
- Flour
- Thickens the soup when cooked with butter into a paste and stirred into the liquid.
- Cream
- Adds richness, smoothness and a softer, creamy mouthfeel to the finished soup.
- Stock
- Forms the liquid base that cooks the asparagus and carries the soup's flavour.
The step that matters
Adding the butter and flour paste. Flour must be cooked in the hot liquid while stirring constantly; otherwise it clumps into lumps and tastes raw, and the soup will not thicken smoothly.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, flour, cream):
- Leekfits better
- Arrowrootfits better
- Chivefits better
- Asparagusthe original
Fit is the average pairing score against butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
