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 ↓
Deviled Clams
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Boil the clams in their own juice until reduced.
Add cream, butter, salt, pepper, onion, and parsley to the clams.
Mix cornstarch with a little milk and add to the clam mixture.
Stir in the chopped hard-boiled eggs.
Remove the mixture from heat.
Beat one egg and mix the beaten egg into the clam mixture.
Bake and serve
Spoon the mixture into clam shells.
Cover the shells with bread crumbs.
Bake in a 400°F (200°C) oven until browned.

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 body and flavor of the filling.
- Cream
- Adds richness and a smooth, moist texture to the filling.
- Eggs
- Bind the filling and set when baked, giving it structure.
- Cornstarch
- Thickens the clam mixture so it holds together in the shells.
- Butter
- Adds fat for richness and helps the topping brown.
- Bread crumbs
- Form a crisp, browned topping over the filling.
The step that matters
Remove the mixture from heat before adding the beaten egg. Egg proteins set and can scramble if the mixture is too hot, leaving a grainy texture instead of a smooth, bound filling. Letting it cool slightly before mixing in the egg keeps the filling creamy.
Swap the onion
How well each one fits the dish's main ingredients (clam, cream, butter, pepper, parsley, milk, egg):
- Potatofits better
- Capsicumfits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against clam, cream, butter, pepper, parsley, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
