Why it works: Milk and butter 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 Creah Soup
Ingredients
Directions
Prepare the asparagus
Cut off the ends of the asparagus for about two inches and boil the rest until tender.
Rub the cooked asparagus through a coarse sieve and season the pulp with coarse sea salt.
Meanwhile, boil the asparagus ends for about fifteen minutes, then drain them.
Make the soup
Boil the milk in a saucepan.
Mix the butter and flour together, then stir into the boiling milk.
Add the asparagus pulp to the milk mixture and boil for about ten minutes, stirring constantly.
Serve
Place the drained asparagus ends in a soup tureen.
Add the cream to the soup and pour it into the tureen without boiling again.
Serve immediately.

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
- Forms the main body and flavour of the soup once rubbed into a smooth pulp.
- Milk
- Forms the liquid base of the soup and carries the asparagus flavour.
- Butter and flour
- Thicken the milk slightly, giving the soup body.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
The step that matters
Adding the cream without boiling. Cream can curdle or separate when boiled, and boiling also thins its texture. Adding it off the heat keeps the soup smooth and rich.
Swap the asparagus
How well each one fits the dish's main ingredients (milk, butter, flour, cream):
- Potatofits better
- Leekfits better
- Arrowrootfits about as well
- Asparagusthe original
Fit is the average pairing score against milk, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
