Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Clam Soup
Ingredients
Directions
In a pot, combine the clam liquor and water, then add the chopped clams.
Bring to a boil and cook for 30 minutes.
Season with pepper, coarse sea salt, and add the butter.
Bring to a boil again, then stir in the boiling hot milk.
Mix in the flour or crushed crackers until smooth.
If desired, add a pinch of mace and a splash of lemon juice for extra flavor.

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 savory flavor and tender bite of the soup.
- Milk
- Forms the creamy body of the soup as the base liquid.
- Butter
- Adds richness and a silky mouthfeel to the broth.
- Flour
- Thickens the milk and broth so the soup becomes smooth and creamy.
The step that matters
Mix in the flour or crushed crackers until smooth. Flour needs to be mixed with cold milk first and stirred into the hot liquid so it disperses evenly. Added dry or in lumps, it clumps and the soup stays grainy instead of thickening smoothly.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (clam, pepper, butter, egg, milk, flour, lemon):
- Parsleyfits better
- Nutmegfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against clam, pepper, butter, egg, milk, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
