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 mashes into a soft, fluffy texture.
- Butter
- Adds fat and richness, giving the mash a smooth, silky mouthfeel.
- Milk or cream
- Adds moisture and softness, loosening the mash to a light, smooth consistency.
The step that matters
Mash until light and smooth. Overworking warm potatoes can make them gluey, while stopping too early leaves lumps. Adding hot liquid and butter while mashing helps the starch absorb fat and moisture evenly for a smooth, light result.
