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 ↓
Scalloped Clams
Ingredients
Directions
The book says “a very hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the clams
Wash the clam shells and place them in a saucepan over heat with a close cover until the shells open.
Make the filling
In a skillet, fry the chopped onion in butter until light brown.
Stir in the flour and then add the chopped clams, milk, salt, nutmeg, and cayenne pepper.
Gently stew the mixture for 30 minutes.
Remove the saucepan from heat and stir in the egg yolks.
Bake and serve
Arrange clean clam shells or small dishes in a large dripping pan.
Pour the mixture into the shells and bake in a very hot oven (400°F / 200°C) until slightly browned.
Serve hot on warm plates.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main body and savoury flavour of the filling.
- Butter
- Adds richness and carries the onion flavour while it browns gently.
- All-purpose flour
- Thickens the milk into a smooth sauce that holds the filling together.
- Milk
- Forms the creamy liquid that bakes into a soft, moist custard.
- Egg yolks
- Enrich the filling and help it set into a tender, custard-like texture.
The step that matters
Stirring in the egg yolks off the heat. Egg yolks begin to set at moderate heat, so adding them to a hot mixture off the heat, rather than boiling it afterward, prevents curdling and keeps the filling smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (clam, butter, flour, milk, nutmeg, pepper, egg):
- Potatofits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against clam, butter, flour, milk, nutmeg, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
