Serve hot with your choice of meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the starchy base that mashes into a soft, fluffy body.
- Butter
- Adds fat for richness and a smoother, silkier mouthfeel.
- Cream or milk
- Adds moisture and dairy fat, loosening the mash and making it creamy.
The step that matters
Beating in the cream or milk. Overbeating cooked potatoes releases excess starch, which turns the mash gluey and sticky. Beat just until smooth and foamy, and warm the cream or milk first so the potatoes stay hot and absorb it evenly.
