Why it works: Pepper and parsley 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 Chowder
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Butter a deep tin basin and coat it with soaked soda biscuits.
Layer
Sprinkle pepper and bits of butter over the biscuits.
Add a double layer of clams, season with pepper, and add more butter.
Layer soaked biscuits again, followed by clams and butter.
Pour in the milk or water and top with another layer of soaked biscuits.
Bake
Cover with a plate and bake for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soda biscuits
- Soak and layer to form a soft, absorbent base that holds the clams and liquid together.
- Clams
- Provide the main seafood flavor and savory body of the dish.
- Butter
- Adds richness and moisture as it melts through the layers during baking.
- Milk or water
- Supplies liquid that softens the biscuits and creates a moist, steamed texture.
The step that matters
Cover with a plate and bake for 45 minutes. Covering traps steam so the biscuits soften and the clams cook gently in the liquid. Uncovered, the top can dry out before the layers are cooked through.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (butter, biscuit, clam, pepper, milk):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits less well
- Thymefits less well
Fit is the average pairing score against butter, biscuit, clam, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
