Why it works: Asparagus and parsley match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 566 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Asparagus Sauce
Ingredients
Directions
Prepare the asparagus
Break the asparagus in the tender part.
Wash the asparagus well.
Place the asparagus in boiling salted water until green.
Once tender, remove the asparagus and place in cold water.
Drain the asparagus on a cloth until dry.
Make the sauce
In a saucepan, melt the butter with the parsley and onions.
Add the asparagus to the saucepan and fry over high heat for 5 minutes.
Add salt, sugar, and sauce tournee.
Simmer for another 5 minutes.
Rub the mixture through a fine sieve.
If the color is not good, add a little spinach green.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 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 body of the sauce and gives it its main flavour.
- Butter
- Carries flavour and gives the sauce a rich, smooth mouthfeel.
- Sauce tournee
- Adds body and thickening to the sauce.
The step that matters
Rub the mixture through a fine sieve. Pushing the cooked asparagus through a fine sieve breaks down the fibres and removes stringy pieces, giving the sauce a smooth, even texture.
Swap the parsley
How well each one fits the dish's main ingredients (asparagus, butter, onion, sugar, sauce):
- Capersfits better
- Garlicfits better
- Tarragonfits better
- Parsleythe original
Fit is the average pairing score against asparagus, butter, onion, sugar, sauce. Candidates are from the same food group and used in at least 100 recipes.
