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 ↓
Oyster Soup
Ingredients
Directions
Make the broth
Wash the veal in cold water and place it in a soup kettle with enough cold water to cover it.
Skim the surface as it heats until nothing rises.
Cover and boil slowly for 3 hours.
After 1 hour, add the celery root, then the parsley.
Add the oysters and serve
In a separate saucepan, heat the oysters with ½ cup of cold water until scalding hot, but do not boil.
Pour the oysters into a colander over a dish to catch the liquid.
Add the oyster liquid to the soup kettle, then season with salt and pepper.
Add the dumplings and cook for 5 minutes, then gently stir in the oysters.
Do not let the soup boil after adding the oysters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of veal
- Simmers slowly to release flavor and gelatin, giving the broth body.
- Oysters
- Add a briny, savory flavor to the finished soup.
- Celery root
- Adds a mild, earthy celery flavor to the broth.
The step that matters
Do not let the soup boil after adding the oysters. Boiling toughens oysters, making them rubbery and shrinking them, and can cause the delicate oyster flavor to be lost. Keeping the soup just below a boil keeps them tender.
