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 soup base
Cut the green tops from the asparagus and set aside.
Heat the butter in a pot and mix in the flour.
Add 1 quart of the stock and the white parts of the asparagus.
Boil for 30 minutes or until tender.
Strain and combine
Pass the mixture through a fine sieve and rub through the pulp.
In another pot, boil the green tops in the remaining stock for 15 to 20 minutes.
Combine this with the soup and reheat.
Serve
Pour over the cream in a serving tureen.
Add salt to taste.
Add a little more Liebig Company's Extract of Meat for extra flavor.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main flavor and, once puréed, the body of the soup.
- Butter
- Adds fat for richness and carries the flavor of the vegetables.
- Flour
- Thickens the soup as its starch swells in the hot liquid.
- Stock
- Forms the liquid base that carries and dissolves the flavors.
- Cream
- Adds richness and a smooth, velvety texture.
The step that matters
Mixing the flour into the butter. Cooking flour in melted butter coats the starch granules with fat, so they disperse evenly when liquid is added. Adding the flour without this step tends to produce lumps and an uneven, floury thickness.
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.
