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 softens and fluffs into the mashed texture.
- Butter
- Adds fat and richness, giving the mash a smooth, silky mouthfeel.
- Milk
- Adds moisture and loosens the mash so it spreads smoothly.
The step that matters
Mash until smooth. Cooked potato starch ruptures easily; overworking it releases excess starch and turns the mash gluey, while stopping early leaves lumps. Mash gently and add the butter and milk before mashing so they blend evenly.
