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 when boiled and gives the mash its body.
- Butter
- Adds fat for richness and a smoother, silkier mouthfeel.
- Milk
- Adds moisture and loosens the mash to a creamy consistency.
The step that matters
Mash until smooth and creamy. Overworking the potatoes releases excess starch, which can make the mash gluey. Mash just until smooth, and add the butter and milk warm if possible so they blend in evenly.
