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
Peel the potatoes and soak them in cold water for 30 minutes.
Boil the potatoes in plenty of salted water until a fork easily penetrates the largest one.
Drain the potatoes and dry them thoroughly.
Mash and serve
Mash the potatoes with a fork or split spoon until powdery.
Mix in hot milk with melted butter and salt to taste, beating until creamy.
Transfer to a hot, deep dish, leaving the top rough.

What each ingredient does
- Potatoes
- Starch provides the bulk and fluffy, absorbent body of the mash.
- Butter
- Fat adds richness and a smooth mouthfeel to the mashed potatoes.
- Hot milk
- Liquid loosens the mash and, with the butter, makes it creamy.
The step that matters
Drain and dry the potatoes thoroughly. Surface water left on the boiled potatoes dilutes the mash and makes it gluey or soggy. Drying lets the starch stay fluffy when mashed and absorb the milk and butter evenly.
