Why it works: Cream and butter 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 ↓
Potatoes — Mashed
Ingredients
Directions
Cook the potatoes
Peel the potatoes thinly and place them in boiling water with a little salt.
Cook until tender, then drain the water.
Remove the cover for a few moments to dry the potatoes.
Transfer the potatoes to a heated earthen dish.
Mash and serve
Beat the potatoes with a wire beater or silver fork, adding cream or milk and butter to moisten.
Season with salt to taste and mold into the desired shape before serving.

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 and fluffy when cooked and mashed.
- Cream (or milk)
- Adds moisture and richness, loosening the mash and softening its texture.
- Butter
- Adds fat for richer flavour and a smoother, silkier mouthfeel.
The step that matters
Drying the potatoes after draining. Letting surface water evaporate keeps the mash from turning wet and gluey. Excess water dilutes the starch and makes the texture loose, so the potatoes should be dry before they are beaten.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter):
- Potatothe original
- Onionfits about as well
- Leekfits less well
- Chivefits less well
Fit is the average pairing score against cream, butter. Candidates are from the same food group and used in at least 100 recipes.
