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 fluffy when mashed and forms the bulk of the dish.
- Butter
- Adds fat and richness, coating the starch for a smoother, silkier texture.
- Milk
- Adds moisture and loosens the mash, and its warmth keeps the potatoes smooth as they are beaten.
The step that matters
Gradually add boiling milk and beat until smooth. Adding the liquid in portions lets it blend evenly with the starch. Cold or excess liquid added at once can make the mash gluey or runny, and overbeating released starch also turns it gummy.
