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
- Egg yolks
- Form the creamy, rich filling that gives the stuffed whites their body and flavor.
- Butter
- Adds richness and a smooth, silky texture to both the filling and the white sauce.
- Cream
- Adds moisture and softness, loosening the mashed yolks into a spreadable filling.
- Flour
- Thickens the milk into a white sauce by absorbing liquid as it cooks.
- Milk
- Forms the liquid base of the white sauce, which the flour thickens into a smooth coating.
The step that matters
Stir in boiling milk until smooth and thick. Adding the boiling milk to the butter and flour mixture all at once and stirring constantly helps prevent lumps, because the starch in the flour must be dispersed before it thickens.
