Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream of Asparagus Soup
Ingredients
Directions
Make the soup base
Combine beef stock, asparagus, onion, celery, and parsley in a pot.
Cook the mixture for 30 minutes.
Rub the mixture through a puree sieve to remove solids.
Season with salt and pepper to taste.
Finish and serve
Whisk together the egg yolks and cream in a bowl.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main vegetable flavor and body of the soup.
- Egg yolks
- Thicken the soup and give it a silky, rich texture when gently heated.
- Thin cream
- Adds richness and smoothness, softening the soup's flavor and mouthfeel.
- Beef stock
- Forms the liquid base that carries the asparagus flavor.
The step that matters
Stir constantly until just boiling. Egg yolks can scramble and curdle if the soup overheats or boils too long after tempering. Constant stirring and stopping at a light boil keeps the custard-like texture smooth.
Swap the onion
How well each one fits the dish's main ingredients (beef, asparagus, celery, parsley, pepper, egg, cream):
- Carrotfits better
- Spinachfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against beef, asparagus, celery, parsley, pepper, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
