Potato granules are a dehydrated potato product prepared by drying cooked potatoes in an add-back process in a ring dryer, causing (clumps of?) potato cells to fall apart by itself. Nowadays potato granules are a less common product than potato flakes. Potato granules have a higher specific density than potato flakes and cells are less damaged. This results in a less sticky mash, but may make them less suitable for snack extrusion, where the stickiness may be an asset.
