Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Asparagus Soup
Ingredients
Directions
Prepare the asparagus
Scrape the asparagus and cut off 1 inch from the tops.
Soak the tops in water.
Make the soup
Chop the stalks and place them in a pot with the bacon, chopped onion, salt, and pepper.
Add 2 quarts of water and boil until the stalks are soft.
Pulp the mixture through a sieve and return the liquid to the pot.
Add the cut-up chicken and the reserved asparagus tops.
Boil until cooked through.
Thicken the soup with flour, butter, and milk, then serve.

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, once pulped, the body of the soup.
- Bacon
- Adds fat and savoury flavour to the stock as it cooks.
- Onion
- Adds aromatic sweetness and depth to the base.
- Chicken
- Adds meat flavour and richness to the broth.
- Flour
- Thickens the soup, giving it a fuller texture.
The step that matters
Thicken the soup with flour, butter, and milk. Flour needs to be cooked into the fat and hot liquid to avoid lumps and a raw starchy taste. Adding it to boiling soup without first blending it smoothly with butter can cause clumping, so it should be whisked in gradually.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, pepper, chicken, flour, butter, milk):
- Potatofits better
- Leekfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against asparagus, pepper, chicken, flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
