Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Deviled Crabs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Open the can of crabs and drain the water into a bowl.
In a separate bowl, rub together the butter and flour.
Pour the mixture into the boiling milk and cook for 2-3 minutes.
Season with cayenne pepper and salt, then remove from heat.
Add the crab meat, mustard, lemon juice, mashed yolks, chopped whites of the hard-boiled eggs, and beaten raw egg, then mix thoroughly.
Fill the crab shells with the mixture.
Bake and serve
Brush the tops with the yolk of the egg.
Sprinkle with bread crumbs.
Pour a tablespoon of milk or cream over each.
Brown in the oven at 400°F (200°C) and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crabs
- Provides the main body and flavor of the filling.
- Flour
- Thickens the butter and milk into a smooth, creamy sauce that holds the filling together.
- Milk
- Forms the creamy base of the sauce and keeps the filling moist.
- Eggs
- Bind the filling and set when baked, giving it a firmer texture.
- Lemon juice
- Adds acidity that brightens the rich, creamy filling.
- Mustard
- Adds a sharp flavor that cuts through the richness of the butter and cream.
The step that matters
Thickening the sauce. The butter and flour mixture must be added to the boiling milk and cooked briefly so the starch thickens fully and loses its raw floury taste. Stirring it in well helps prevent lumps.
Swap the mustard
How well each one fits the dish's main ingredients (crab, butter, flour, milk, pepper, lemon, egg):
