Why it works: Milk and butter 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid body of the soup and, once thickened, its creamy texture.
- Butter
- Adds fat and richness, and forms the base with flour for thickening.
- Flour
- Thickens the liquid when cooked with butter, giving the soup body.
- Oyster liquor
- Supplies the briny, savoury flavour of the oysters to the soup.
- Oysters
- Provide the main flavour and protein of the soup and cook briefly in the hot liquid.
The step that matters
Serve as soon as the oysters puff and curl. Oysters toughen and shrink when overcooked, so they should be removed from heat as soon as the edges curl to keep them tender.
