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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body of the scallop, with yolks and whites adding richness and texture.
- Flour
- Thickens the butter and milk into a smooth sauce that holds the layers together.
- Butter
- Enriches the sauce and helps the flour cook into a smooth base.
- Milk
- Forms the liquid base of the sauce, which thickens as it boils.
- Cold boiled ham
- Adds savory, salty flavor and chewy texture between the egg layers.
The step that matters
Boil the sauce until it thickens. The flour needs to cook long enough to thicken the milk fully and lose its raw starchy taste. Stopping early leaves a thin sauce that will not hold the layers together, and stirring prevents lumps.
