Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Bisque of Clams
Ingredients
Directions
Prepare the clams
Place clams with their liquor and water in a porcelain kettle over medium heat.
When they start to simmer, remove clams, mince them, and set aside.
Make the soup
Add minced clams back to the kettle with onion, parsley, and mace.
Simmer for 15 minutes.
Strain the mixture.
Return the liquid to the kettle with stock.
Thicken and finish
Mix flour and butter together.
Slowly pour the soup over the flour and butter mixture, stirring until creamy.
Add hot cream and a little cayenne, ensuring the soup does not boil after adding the cream.

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 bisque.
- Flour
- Thickens the soup into a smooth, creamy texture when mixed with butter.
- Butter
- Adds richness and fat that carries flavor and smooths the texture.
- Cream
- Adds richness and a silky, smooth mouthfeel to the finished soup.
- Stock
- Forms the savory liquid base that gives the bisque depth of flavor.
The step that matters
Do not boil after adding the cream. Once cream is added, boiling can cause it to curdle or separate and make the texture grainy, so the soup should be kept hot but not boiling.
Swap the mace
How well each one fits the dish's main ingredients (clam, onion, parsley, flour, butter, cream):
- Garlicfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against clam, onion, parsley, flour, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
