Why it works: Pepper and thyme are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Oyster Soup
Ingredients
Directions
Make the broth
In a large pot, combine the washed oysters, water, chopped onions, ham, pepper, and salt.
Boil until the liquid is reduced by half, then strain through a sieve.
Return the liquid to the pot and add the fresh oysters.
Boil until the fresh oysters are cooked through.
Thicken and serve
Thicken the soup by whisking in the flour, cream, and beaten egg yolks.
Boil for a few minutes, ensuring it does not curdle and the flour is lump-free.
If desired, add a little thyme, but do not boil long enough to discolor the soup.
Serve with the last oysters added to the soup.

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 body of the soup, with fresh oysters added for texture.
- Flour
- Thickens the soup as it heats, giving it a smooth, lump-free body.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the soup.
- Egg yolks
- Enrich and thicken the soup, though they can curdle if overheated.
- Onions
- Build a savory aromatic base as they simmer in the broth.
The step that matters
Adding the egg yolks and cream. Egg yolks thicken by gentle heat; if the soup boils hard after they are added, the proteins can scramble and curdle. Keep it just below a boil and stir steadily.
Swap the thyme
The recipe marks thyme as optional. How well each one fits the dish's main ingredients (oyster, onion, ham, pepper, flour, cream, egg):
- Nutmegfits better
- Parsleyfits better
- Capersfits better
- Thymethe original
Fit is the average pairing score against oyster, onion, ham, pepper, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
