Pulverizing potatoes is a cooking technique that involves breaking down the potatoes into a fine, powdery consistency. This can be done by using a food processor, blender, or even a potato masher. The term 'pulverize potatoes' can also refer to mashing the potatoes, which is a process of breaking them down into a thick, creamy texture. Mashing is typically done with a potato masher, but can also be done with a fork or other kitchen utensil.
