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

What each ingredient does

Parsnips
Provides the starchy base that gives the mash its body and bulk.
Cream
Adds moisture and a smooth, loose texture to the mash.
Butter
Adds fat for richness and a silkier mouthfeel.

The step that matters

Boil the parsnips until tender. Parsnips that are not fully softened will mash unevenly and leave lumps. Cooking them through breaks down their starch cells so the mash becomes smooth when combined with the cream and butter.
