Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Pie of Oysters and Sweet-breads
Ingredients
Directions
Prepare
Boil the sweetbread in salted water for 20 minutes.
Transfer to cold water, drain, and cut into small pieces, removing all skin and strings.
Strain the oysters, saving the liquor.
Make the sauce
In a saucepan, melt the butter, add the flour, and bring to a boil.
Stir in the cream and oyster liquor, and boil for 1 minute.
Assemble and bake
Line a baking dish with puff pastry, layer in the oysters, then the sweetbread, and pour the sauce over.
Cover with pastry and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbread
- Provides the tender, rich meat that forms the body of the filling.
- Oysters
- Supply the briny, savoury flavour that defines the filling.
- Butter
- Adds fat and richness, and helps form the base of the sauce.
- Flour
- Thickens the butter and cream into a smooth sauce that holds the filling together.
- Cream or milk
- Adds moisture and richness, giving the sauce a smooth, creamy body.
- Puff pastry
- Forms a flaky, golden crust that encloses the filling.
The step that matters
Boiling the sauce after adding the cream and oyster liquor. Flour only thickens fully when it is heated long enough to cook out its raw taste and swell with the liquid. Boiling for the stated minute activates the starch so the sauce sets properly rather than staying thin or floury.
