Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Deviled Crabs
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, combine crabs, bread crumbs, vinegar, butter, mustard, salt, black pepper, cayenne pepper, hard‑boiled egg yolks, and the beaten raw egg. Mix well until combined.
Fill the crab shells with the mixture.
Bake and serve
Top with additional bread crumbs and small bits of butter.
Bake until heated through and golden brown.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crabs
- Forms the main body of the filling and provides the seafood flavor.
- Bread crumbs
- Absorb liquid and give the filling body, and form a crisp, browned topping.
- Raw egg
- Binds the filling so it holds its shape when baked.
- Hard-boiled egg yolks
- Add richness and a creamy texture to the filling.
- Butter
- Adds fat and richness, and helps the topping brown.
- Vinegar
- Adds acidity that brightens the rich, creamy filling.
The step that matters
Bake until heated through and golden brown. Baking too briefly leaves the filling cold in the centre, while overbaking dries it out. The raw egg must be heated fully to set the binder, and the bread-crumb and butter topping browns through Maillard reactions, so watch colour and texture rather than the clock alone.
Swap the mustard
How well each one fits the dish's main ingredients (crab, bread, vinegar, butter, pepper, egg):
- Capsicumfits better
- Mustardthe original
- Asparagusfits about as well
- Chivefits about as well
Fit is the average pairing score against crab, bread, vinegar, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
