Why it works: Asparagus and spinach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 274 recipes. Both carry 2-methoxy-4-vinylphenol, which smells clove, smoky. The science ↓
Asparagus Soup
Ingredients
Directions
Prepare
Cut off the tips of the asparagus and set aside.
Trim the stalks and cut them into small pieces.
Wash and pick the spinach.
Make the soup
In a stewpan, bring the stock or water to a boil.
Add the asparagus and spinach, and cook until tender, about 40 minutes.
Rub through a fine sieve.
Melt the butter in the stewpan, sprinkle in the flour, and stir in the milk until it boils.
Add the asparagus and spinach puree, season with salt and pepper, and simmer gently for 10 minutes.
Cook the tips and serve
In a small saucepan, bring water to a boil, add a little salt, and cook the asparagus tips for 10 to 15 minutes.
Place the asparagus tips in a tureen, add the cream and adjust seasoning, 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 puréed, the body of the soup.
- Spinach
- Adds colour and body to the purée, thickening the soup as it breaks down.
- Flour
- Thickens the milk with butter into a smooth base that gives the soup body.
- Milk
- Adds creaminess and softness, rounding out the vegetable flavour.
- Butter
- Adds fat and richness and helps form the flour-thickened base.
- Cream
- Added at the end to enrich the texture and mellow the soup.
The step that matters
Rub through a fine sieve. Pushing the cooked asparagus and spinach through a fine sieve removes fibres and skins, giving a smooth purée. Skipping or rushing this step leaves the soup stringy and gritty.
