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 ↓
Crabs Scalloped
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 the crab and eggs
Boil the crabs until the shells are red, then remove the meat, discarding the stomach, intestine, and soft fins, but saving the green fat and curd.
Chop the hard-boiled eggs finely and set aside.
Make the sauce
In a saucepan, melt the butter and flour over medium heat until bubbling.
Gradually stir in the milk and bring to a boil, then season with salt, pepper, and cayenne.
Add the crab meat, chopped eggs, and lemon juice and rind, and heat together.
Bake and serve
Transfer the mixture to scallop shells or a suitable dish.
Sprinkle cracker crumbs on top and brown in a hot oven at 400°F (200°C).
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab
- Provides the main body and flavour of the filling.
- Hard-boiled eggs
- Add richness and body to the filling.
- Butter and flour
- Form a roux that thickens the milk into a smooth sauce.
- Milk
- Forms the liquid base of the sauce, giving it creaminess.
- Lemon
- Adds brightness and acidity that cuts the richness of the sauce.
The step that matters
Thickening the sauce. Cook the butter and flour until bubbling before adding milk, then bring the milk to a boil while stirring. This cooks out the raw flour taste and lets starch swell fully, so the sauce thickens smoothly without lumps.
