Why it works: Asparagus and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,968 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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.

Pepper and sugar barely smell alike, yet cooks put them together in 19,401 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
- Forms the main body and flavor of the soup; pressing it thickens the liquid and the pieces add texture.
- Stock
- Provides the liquid base that carries the asparagus flavor.
- Sugar
- Adds a touch of sweetness that balances the vegetal taste of the asparagus.
The step that matters
Pressing the asparagus through a sieve. Pushing the cooked asparagus through a fine sieve breaks down its fibers and releases starch and pulp, which give the soup its body. Skipping or rushing this step leaves the soup thin and stringy.
Swap the asparagus
How well each one fits the dish's main ingredients (pepper, sugar):
- Capsicumfits better
- Mustardfits better
- Carrotfits better
- Asparagusthe original
Fit is the average pairing score against pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
