Why it works: Parsley and mint are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,198 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Asparagus Pease for the Second Course
Ingredients
Directions
Prepare
Pick and cut young asparagus into small, equal pieces, discarding woody parts.
Boil asparagus in salted water, then drain and dry with a cloth.
Make the sauce
Fry asparagus in butter with parsley, green onions, and mint.
Dredge flour over the mixture, add sugar, and moisten with boiling water.
Boil quickly, then remove the parsley and onion bundle.
Thicken the sauce with beaten egg yolks mixed with cream or melted butter, salt, and grated nutmeg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young asparagus
- Forms the main vegetable body of the dish and carries its fresh flavour.
- Butter
- Adds fat and richness while frying, carrying the herb aroma through the dish.
- Flour
- Dredged over the mixture to thicken the liquid into a cohesive sauce.
- Egg yolks
- Thicken the sauce on gentle heating and add richness and body.
- Cream or melted butter
- Adds fat and smoothness, enriching the sauce and softening its texture.
The step that matters
Thicken the sauce with egg yolks. Egg yolks thicken through gentle heat; if the sauce boils after they go in, the proteins can scramble and curdle, leaving a grainy texture instead of a smooth sauce.
Swap the mint
How well each one fits the dish's main ingredients (asparagus, butter, parsley, onion, flour, sugar, egg):
- Capersfits better
- Tarragonfits better
- Nutmegfits better
- Mintthe original
Fit is the average pairing score against asparagus, butter, parsley, onion, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
