Why it works: Butter and bread 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 ↓
Scalloped Crab
Ingredients
Directions
Prepare the crab
Pick all the meat from the crab, leaving the small claws.
Scald the large shell, rub it with coarse sea salt (formerly 'bay salt') to cleanse, and then dry it.
Make the filling
Melt the butter in a pan, add the flour, and gradually stir in the milk until boiling.
Add the anchovy and seasonings, then stir in the picked crab and heat through.
Fill and garnish
Fill the crab shell with the mixture, sprinkle brown crumbs on top, and garnish with the small claws standing upright.
Rub the hard-boiled egg through a sieve over the dish and finish with a few sprigs of parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and adds richness and flavour to the filling.
- Flour
- Thickens the milk into a smooth white sauce that binds the crab.
- Milk
- Forms the liquid base of the sauce, giving the filling its creamy moisture.
- Crab
- Provides the main meat, the flavour and texture at the centre of the dish.
- Anchovy
- Adds savoury depth and salty umami to the sauce.
- Bread crumbs
- Form a crisp, golden browned topping over the filling.
The step that matters
Thickening the milk sauce. Flour must be cooked into the melted butter and milk brought to a boil gradually, or lumps form and the sauce stays raw-tasting. Stirring steadily keeps it smooth and properly thickened before the crab goes in.
