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 from the shells, 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 for a moment.
Season the sauce with salt, pepper, and cayenne, then add the crab meat, chopped eggs, and lemon juice and rind.
Heat the mixture together, then transfer it to scallop shells or a suitable baking dish.
Bake and serve
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 meat
- Provides the main flavour and the bulk of the filling.
- Milk
- Forms the liquid base of the sauce that binds the filling together.
- Butter and flour
- Flour thickens the butter into a roux that gives the sauce body.
- Hard-boiled eggs
- Add richness and body to the filling as they are stirred through.
- Cracker crumbs
- Form a crisp topping that browns in the hot oven.
The step that matters
Cooking the roux and milk sauce. Flour must bubble in the melted butter so its starch is cooked out, and the milk must be added gradually while stirring to avoid lumps and a thin, pasty sauce.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
