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 ↓
Scalloped Crabs
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 meat from the shells of the crabs, discarding the stomach, intestine, and soft fins, but saving the green fat and curd.
Chop the hard-boiled eggs finely and grate the lemon rind.
Make the sauce
In a saucepan, melt the butter and flour over medium heat until bubbling.
Gradually stir in the milk and bring the sauce to a boil.
Combine and bake
Season the sauce with salt, pepper, and cayenne, then add the crab meat, chopped eggs, and lemon juice.
Heat the mixture together, then transfer it to scallop shells or a serving dish.
Dust the tops with cracker crumbs 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 meat
- Forms the main body of the dish and gives its sweet, delicate flavor.
- Hard-boiled eggs
- Add body and richness to the filling, giving it a softer, more substantial texture.
- Butter
- Adds fat and flavor and forms the base of the roux with the flour.
- Flour
- Thickens the milk into a smooth sauce that holds the filling together.
- Milk
- Forms the liquid base of the sauce, adding creaminess.
- Lemon juice
- Adds acidity that brightens the rich sauce and crab flavor.
The step that matters
Gradually stirring the milk into the butter and flour. Adding the liquid slowly while stirring keeps the starch dispersed, so the sauce becomes smooth instead of lumpy. The starch must then come to a boil to fully thicken.
