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 ↓
Oyster Soup
Ingredients
Directions
Make the soup
In a pot, combine water or liquor from boiled fowl with oysters, salt, and pepper.
In a small bowl, mix butter and flour until smooth, then add to the pot.
Beat the egg yolks and mix with sweet milk and strained oyster liquor, then add to the pot.
Cook for a few minutes until heated through.
Serve
Pour the soup into a tureen over slices of dry toasted bread and serve 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 of the soup.
- Egg yolks
- Enrich the soup and thicken it gently as they heat.
- Butter
- Adds richness and fat that carries flavor through the broth.
- Flour
- Thickens the soup slightly when cooked with the butter and liquid.
- Sweet milk
- Adds creaminess and softens the briny oyster flavor.
The step that matters
Adding the egg yolk and milk mixture. Egg yolks can curdle or scramble if the soup is boiling when they are added. Keeping the heat gentle and stirring while adding them helps the soup stay smooth and creamy.
