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 ↓
Bisque of Crabs
Ingredients
Directions
Prepare the crabs
Boil the crabs for 30 minutes, then strain and let cool.
Break apart the crabs and pick out the meat.
Make the soup
In a mortar, pound the under-shell and claws with the rice and butter until smooth.
Transfer this mixture to a saucepan and add the stock, herbs, salt, and peppers.
Boil slowly for 1 hour, then pour through a sieve, working as much pulp through as possible.
Keep the soup warm but not boiling, then slowly stir in the warm milk and beaten egg yolk.
Season to taste.
Serve
Heat the crab meat in a little boiling water, drain, and place in a hot tureen.
Pour the soup over the crab meat and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crabs
- Provide the meat and the shells that build the flavour of the bisque.
- Butter
- Adds richness and fat, carrying flavour and giving the soup a smooth mouthfeel.
- Cold boiled rice
- Thickens the soup as it is pounded and pressed through the sieve, adding body.
- Stock
- Forms the liquid base of the soup.
- Egg yolk
- Enriches and thickens the finished soup, adding richness and smoothness.
- Milk
- Adds creaminess and mildness, softening the soup's flavour.
The step that matters
Keep the soup warm but not boiling before adding the milk and egg yolk. Egg yolk thickens by gentle heat and curdles if it boils, so the soup must stay below boiling when the yolk and milk are stirred in slowly.
