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 ↓
Mashed Potatoes
Ingredients
Directions
Prepare the potatoes
Boil and dry the potatoes.
Mash the potatoes in the same dish they were boiled in.
Add the dairy and serve
Heat the milk or cream with the butter and salt.
Slowly add the heated mixture to the potatoes while beating continuously.
When light and foamy, pile into a hot serving dish without smoothing over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, mashing into a soft, starchy base.
- Milk or cream
- Adds moisture and richness, softening the mash into a smooth texture.
- Butter
- Adds fat for richness and a silkier mouthfeel.
The step that matters
Slowly add the heated mixture while beating. Adding the hot liquid gradually while beating lets the potato starch absorb it evenly, producing a smooth, light mash instead of a sticky or lumpy one.
