Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Their starch gives the mash its body and fluffy structure once mashed.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Milk
- Adds moisture that loosens the mash and makes it creamy.
The step that matters
Beat the milk into the potatoes gently. Potato starch releases more when it is worked vigorously, and overbeating makes mashed potatoes gluey and heavy. Beat only until the mash is light and creamy.
