Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Prepare
Boil or steam the potatoes for 30 minutes.
Transfer them to a basin and mash with a wooden spoon until smooth.
Finish and serve
Add salt, butter, and cream or hot milk.
Place the basin in a saucepan of boiling water and beat the mixture for 5 minutes.
Serve on a very hot dish, shaped into a rough cone or smoothed with a knife.

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, with starch that gives the mash its body.
- Butter
- Adds fat and richness, coating the starch for a smoother, silkier texture.
- Cream or hot milk
- Adds moisture and softness, loosening the mash to a smooth consistency.
The step that matters
Beating over boiling water. Beating the mash over simmering water keeps it hot while the starch is worked, so it becomes smooth and fluffy. Cold potatoes turn stiff and gluey, and overworking the starch can make the mash sticky.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream):
- Potatothe original
- Onionfits about as well
- Leekfits less well
- Chivefits less well
Fit is the average pairing score against butter, cream. Candidates are from the same food group and used in at least 100 recipes.
