Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Clam Soup
Ingredients
Directions
Make the broth
Strain the liquor from the clams and place it in a saucepan.
Boil for 10 minutes, skimming well while boiling.
Add 2 quarts of hot water, butter, and parsley.
Finish and serve

Finally, stir in the cream, salt, and cayenne pepper to taste.
Boil for 5 more minutes and serve, being careful not to let the soup curdle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flavour and body of the soup as the chopped seafood.
- Butter
- Adds richness and a silky mouthfeel to the broth.
- Cream
- Adds richness and smoothness, softening the broth's savoury flavour.
The step that matters
Adding the cream and boiling again. Cream can curdle when it is boiled hard or for too long, especially in an acidic or salty liquid. Adding it at the end and keeping the soup at a gentle boil for only 5 minutes helps keep it smooth.
Swap the parsley
How well each one fits the dish's main ingredients (clam, butter, cream, pepper):
- Parsleythe original
- Nutmegfits about as well
- Celeryfits less well
- Garlicfits less well
Fit is the average pairing score against clam, butter, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
