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 clam broth
Combine clam liquor, boiling water, onion, and hard parts of clams in a pot over heat.
Stir gently for 20 minutes after boiling begins.
Strain and season.
Return the mixture to heat with the finely chopped soft parts of clams and simmer for 20 minutes.
Finish and serve
In another vessel, heat the milk until scalding hot.
Stir in the floured butter and cook for 2 minutes.
Add the clam soup to the milk mixture.
Pour into a tureen lined with split Boston crackers dipped in hot milk and buttered.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and body of the soup.
- Milk
- Adds richness and a creamy, smooth texture to the broth.
- Butter
- Adds fat and richness, and with the flour helps thicken the soup.
- Clam liquor
- Carries the concentrated clam flavor that forms the soup base.
The step that matters
Adding the floured butter to the hot milk. Flour mixed into butter must be cooked long enough to lose its raw taste and to thicken smoothly. Stirring it in and cooking for a short time helps prevent lumps and a pasty flavor.
Swap the mace
How well each one fits the dish's main ingredients (clam, milk, butter, flour, parsley, onion, pepper):

Fit is the average pairing score against clam, milk, butter, flour, parsley, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
