Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oyster Soup
Ingredients
Directions
Prepare the oysters
Place 1 quart of oysters in a colander over a bowl and pour ½ cup of cold water.
Heat the liquid to boiling, then strain it and add the oysters.
Cook until the oysters are plump, then remove them with a skimmer and place them in a tureen.
Make the soup
Add ¼ cup of butter, 1 tablespoon of salt, and ½ teaspoon of pepper to the oysters.
Strain the oyster liquor a second time and add it along with 1 quart of scalded milk, 2 slices of onion, and 2 stalks of celery.
Serve
Serve with pieces of toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and tender texture of the soup.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the broth.
- Milk
- Forms the creamy base of the soup and adds body and sweetness.
- Celery
- Adds a subtle aromatic, savory background flavor to the soup.
- Onion
- Adds aromatic depth to the milk as it steeps during cooking.
The step that matters
Cook until the oysters are plump. Oysters cook very quickly; overcooking makes them firm and rubbery, while stopping as soon as their edges curl and they plump keeps them tender.
Swap the celery
How well each one fits the dish's main ingredients (oyster, butter, pepper, milk, onion, bread):
