Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Old potatoes
- Starchy base that mashes into a fluffy, light texture.
- Butter
- Adds fat and richness, and coats the potatoes for a smooth mouthfeel.
- Cream or rich milk
- Adds moisture and fat, giving the mash a creamier, smoother texture.
The step that matters
Add butter while the potatoes are hot. Hot potatoes absorb fat and liquid more readily, so the butter melts in and the mash stays evenly rich. Cooled potatoes turn stiff and gluey when mixed.
