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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that becomes soft, fluffy, and mashable when boiled.
- Hot milk
- Adds moisture and richness, and keeps the mash warm and smooth when whipped in.
- Butter
- Adds fat for richer flavor and a smoother, silkier texture.
The step that matters
Drain and steam the potatoes well. Leftover water dilutes the mash and makes it gluey or loose. Steaming off surface moisture lets the potatoes dry slightly so they absorb milk and butter evenly.
