Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Oyster Soup
Ingredients
Directions
Prepare the oysters
Strain the oysters and bring the liquor to a boil, skimming thoroughly.
Make the base
In a separate saucepan, melt the butter, then add the flour and stir until combined.
Gradually add the milk, stirring until the mixture boils.
Cook and serve
Add the cayenne, salt, black pepper, and oysters (cut into pieces if large).
Pour in the boiling oyster liquor and cook for 5 minutes until the oysters begin to curl.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and tender texture once they curl in the hot soup.
- Butter
- Adds richness and fat, and with the flour forms the base that thickens the soup.
- Flour
- Thickens the butter and milk into a smooth, lightly body-ed base.
- Milk
- Forms the creamy liquid that the thickened base becomes.
The step that matters
Pour in the boiling oyster liquor and cook for 5 minutes. Oysters toughen and shrink when overcooked, so they should be cooked only until they just begin to curl. Watch them closely in the final minutes.
