Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Deviled Clams
Ingredients
Directions
Make the sauce
Fry the sliced onion in butter until light brown, then strain out the onion.
Return the hot butter to the fire and add the chopped tomatoes, salt, sugar, paprika, and nutmeg.
Stir for three minutes, then add the butter rolled in flour.
Assemble and bake
Mix the clams with the butter and tomato mixture.
Fill buttered scallop shells or a buttered pudding dish with the mixture.
Sift fine-crushed crackers over the top and add tiny dabs of butter.
Cook until delicately 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 savory flavor of the filling.
- Butter
- Adds richness and fat, carrying flavor and helping the topping brown.
- Tomatoes
- Provide moisture and acidity that form the base of the sauce.
- Flour
- Thickens the butter and tomato mixture into a smoother sauce.
- Crackers
- Form a crisp, golden crumb topping that browns in the oven.
The step that matters
Cook until delicately browned. The cracker topping and butter dabs brown quickly, so the dish can scorch if left too long. Watching color, not just time, keeps the top golden and the filling hot.
