Potato varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common potato varieties compare.

Variety	Best for
Russet	Mash, fries, baking: high-starch, goes fluffy.
Yukon Gold	All-purpose: creamy mash, roasting, gratins.
Maris Piper / King Edward	UK roasting and chips: fluffy interior, crisp edges.
Charlotte / new potatoes	Salads and boiling: waxy, holds its shape when cooked.

Which should I pick?

For mash, a starchy potato is best: Russet (US) or Maris Piper / King Edward (UK) go light and fluffy; Yukon Gold gives a creamier, buttery mash and is the easiest all-rounder if you only buy one. For salads and boiling where the pieces must hold, use a waxy potato: Charlotte, new potatoes, or red-skinned.
