Why it works: Parsley and arrowroot match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 137 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare the asparagus
Cut the green tops of asparagus to half an inch long.
Boil the asparagus in salted water until tender.
Drain the asparagus on a towel or sieve.
Finish and serve
In a stewpan, combine each tablespoon of asparagus heads with one tablespoon of béchamel sauce, a little sugar, coarse sea salt, and a teaspoon of chopped parsley.
Simmer for a few minutes, then add a little butter rolled in arrowroot. Shake well and serve.

Sauce and butter share little aroma chemistry, yet 15,338 recipes mention both: they likely 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 of the dish and provides its tender texture and fresh flavour.
- Bechamel sauce
- Adds a creamy, rich base that coats the asparagus tips.
- Butter
- Adds richness and a glossy finish to the sauce.
- Arrowroot
- Thickens the sauce so it becomes glossy and clings to the asparagus.
The step that matters
Adding the butter rolled in arrowroot. Arrowroot thickens when heated but can turn gluey or lose its thickening power if overcooked or boiled too long. Adding it near the end while simmering gently keeps the sauce smooth and glossy.

Fit is the average pairing score against asparagus, sauce, sugar, butter, arrowroot. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
