Russet potato

The flesh is white, dry, soft, and mealy, and it is suitable for baking, mashing, and french fries.

[4] Restaurants such as McDonald's use russet potatoes for their size, which produce long pieces suitable for french fries.

As of 2009, "McDonald's top tuber is the Russet Burbank".

[5] The russet Burbank is more expensive than other potatoes, as it consumes more water and takes longer to mature, while it also requires large amounts of pesticides.

[5][6] Varieties with high levels of starch, like russet potatoes, are well-suited to baking and mashing.
