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 ↓

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 finely chopped, body and color to the broth.
- Flour
- Mixed with milk to thicken the soup slightly and give it a smoother body.
- Milk
- Adds richness and creaminess, softening the broth's savory character.
The step that matters
Mixing the milk and flour before adding. Flour clumps if whisked straight into hot liquid. Blending it smoothly into the cold milk first lets it disperse evenly, so the soup thickens without lumps.
Swap the asparagus
How well each one fits the dish's main ingredients (veal, milk, flour, pepper):
- Capsicumfits better
- Carrotfits about as well
- Potatofits about as well
- Asparagusthe original
Fit is the average pairing score against veal, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
