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
Prepare the soup
Drain the liquor from the clams and put it in a pot with 1 cup of water over medium heat.
Add the chopped clams and boil for 30 minutes.
Season with pepper, coarse sea salt, and add the butter.
Bring to a boil again, then stir in the hot milk.
Thicken and finish
Mix the flour with a little cold milk to make a cream and add it to the soup, or use the rolled crackers.
Optionally, add mace and lemon juice to taste.

Flour and butter 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 texture of the soup as they cook in the broth.
- Milk
- Forms the creamy body of the soup and mellows its seasoning.
- Flour
- Thickens the soup into a smooth, creamy consistency when mixed with cold milk first.
- Butter
- Adds richness and a rounded, savory flavor to the finished soup.
The step that matters
Stirring in the flour cream. Flour added directly to hot liquid clumps instead of thickening evenly. Mixing it with cold milk first to form a smooth paste lets the starch disperse and thicken the soup without lumps.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (clam, milk, flour, butter, egg, pepper, lemon):
- Parsleyfits better
- Nutmegfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against clam, milk, flour, butter, egg, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
