Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

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 flavor and, once puréed, the body of the soup.
- Milk
- Adds creaminess and a mild sweetness to the soup.
- Butter
- Adds richness and fat, carrying flavor in the roux.
- Flour
- Thickens the soup by forming a roux with the butter.
The step that matters
Cooking the butter and flour before adding milk. Cooking the flour for a few moments with the butter drives off its raw taste and helps it thicken smoothly. Stirring as the sauce is added keeps lumps from forming.
Swap the asparagus
How well each one fits the dish's main ingredients (milk, butter, flour, pepper, bread):
- Capsicumfits about as well
- Potatofits about as well
- Shallotfits about as well
- Asparagusthe original
Fit is the average pairing score against milk, butter, flour, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
