Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Bisque of Clams
Ingredients
Directions
Prepare the clams
Strain the liquor from the clams and bring it to a boil.
Wash the clams to remove shells and grit.
Scald the clams in their own liquor for 3 minutes, then chop them finely.
Press the clams through a colander or coarse sieve.
Make the soup
In a saucepan, rub the flour and butter together over low heat until blended but not browned.
Gradually stir in the boiling liquor until smooth.
Set the mixture aside to keep hot.
Add all the soft parts to the soup.
Add enough milk or cream to make at least 1 quart of soup.
Thin the soup with more milk if it is too thick.
Season with mace and pepper, being cautious with salt.
Boil the soup for 5 minutes, stirring frequently.
Serve with croutons.

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
- Clams
- Provide the main flavor and the body of the soup once pressed and chopped.
- Butter
- Carries flavor and, blended with flour, forms a roux that thickens the soup.
- Flour
- Thickens the soup when cooked with butter into a roux and stirred into the liquor.
- Milk or cream
- Adds creaminess and volume, and its fat gives the bisque a smooth, rich texture.
The step that matters
Cooking the flour and butter roux. Cooking the flour and butter over low heat until blended but not browned lets starch swell evenly for smooth thickening. Browning adds a darker color and a toasted flavor that changes the bisque's character.
Swap the mace
How well each one fits the dish's main ingredients (clam, butter, flour, milk, pepper):
- Parsleyfits better
- Nutmegfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against clam, butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
