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 ↓
Mashed Potatoes
Ingredients
Directions
Prepare
Boil the potatoes until tender, then drain and steam them dry.
Peel the potatoes and remove any blemishes.
While hot, press the potatoes through a colander or mash them with a wooden fork until smooth.
Finish and serve
In a clean saucepan, melt the butter with the milk or cream.
Add the potatoes and sprinkle with salt, stirring over low heat until well mixed and hot.
Serve immediately, or shape in a dish and brown under the broiler.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Their starch gives the mash its body and fluffy structure once cooked and mashed.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Milk or cream
- Adds moisture and loosens the mash to a smooth, spreadable texture.
The step that matters
Mash the potatoes while hot. Potato starch turns gluey when overworked or when it cools and sets. Mashing hot and stopping once smooth keeps the texture light, and the warm potatoes absorb the butter and milk evenly.
