Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Scalloped Crab
Ingredients
Directions
Prepare the crab
Pick all the meat from the crab, leaving the small claws intact.
Scald the large shell, rub it with coarse sea salt (formerly 'bay salt') to cleanse, and then dry it.
Make the sauce
Melt the butter in a pan, add the flour, and gradually stir in the milk until boiling.
Add the anchovy essence and seasonings, then stir in the picked crab meat and heat through.
Fill and garnish
Fill the crab shell with the mixture, sprinkle breadcrumbs 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 carries flavour while helping the flour form a smooth roux.
- Flour
- Thickens the milk into a smooth white sauce that holds the crab meat together.
- Milk
- Forms the liquid base of the sauce, which thickens as it comes to the boil.
- Crab
- Provides the main meat and sweet, delicate flavour of the dish.
- Hard-boiled egg
- Adds richness and a fine sieved garnish that contrasts with the sauce.
The step that matters
Bringing the sauce to the boil. Flour must be cooked while the milk thickens, otherwise the sauce stays pasty and tastes raw. Stir constantly so lumps do not form and the sauce turns smooth and glossy.
