What does mashed a tuber mean?

"Mashed a tuber" refers to the process of crushing and blending a starchy root vegetable, such as a potato, sweet potato, or yam, until it reaches a smooth or creamy consistency. This culinary technique is often used to create dishes like mashed potatoes, where the tuber is typically boiled first to soften it before mashing. Additional ingredients like butter, milk, or seasonings can be added for flavor and richness.
