Why it works: Celery and pepper 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
Heat the oyster liquor in a pot.
If there's not enough for the soup, add water.
Skim the surface carefully and add the chopped celery.
Boil for a few minutes, then add the milk.
Once it boils, thicken with butter mixed with flour.
Add the oysters and boil for a few minutes.
Season with salt and pepper, then serve immediately.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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
- Oysters
- Provide the main flavor and tender texture; they cook quickly once added.
- Milk
- Forms the creamy body of the soup.
- Butter and flour
- Mixed together to thicken the soup as it boils.
- Celery
- Adds a mild, fresh vegetable flavor to the broth.
- Oyster liquor
- Serves as the flavorful broth base for the soup.
The step that matters
Adding the oysters. Oysters toughen and shrink when boiled too long, so they should be added near the end and cooked only a few minutes until their edges curl.
Swap the celery
How well each one fits the dish's main ingredients (oyster, milk, butter, flour, pepper):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against oyster, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
