Why it works: Mustard and onion match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Deviled Clams
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
Remove the gills from the clams and rinse them.
Make the filling
Chop the hard boiled eggs and mix with the bread crumbs, melted butter, mustard, and chopped onion.
Ensure the mixture is quite wet before baking.
Bake
Fill the clam shells with the mixture and sprinkle additional bread crumbs on top.
Bake in a hot oven at 400°F (200°C) for 30-35 minutes.

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 base that holds the filling in its shells.
- Hard boiled eggs
- Add body and richness, giving the filling a soft, binding texture.
- Bread crumbs
- Absorb moisture and milk, helping the filling hold together and form a crisp topping.
- Melted butter
- Adds fat and richness, helping the topping brown in the oven.
- Onion
- Adds savory aroma and mild sharpness to the filling.
The step that matters
Keep the filling wet before baking. Dry filling bakes stiff and crumbly because the bread crumbs need moisture to soften and bind with the egg and butter. A quite wet mixture keeps the filling moist and tender as it heats.

Fit is the average pairing score against clam, egg, bread, milk, butter, onion. Candidates are from the same food group and used in at least 100 recipes.
