Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Provide the starchy body that mashes into the soft base of the dish.
Butter
Adds fat and richness, giving the mash a smooth, velvety mouthfeel.
Milk or cream
Adds moisture and softness, loosening the mash to a smooth consistency.

The step that matters

Mash the potatoes while still hot. Warm potatoes break down smoothly and absorb butter and milk evenly. Once they cool, starch sets and the mash turns gluey or lumpy.
