It consists of granite stones that rotate inside a drum, crushing the ingredients into a smooth consistency. Wet grinders are commonly used in Indian cuisine for making dishes such as dosa, idli, and various chutneys. They offer efficient grinding with minimal heat generation, preserving the natural flavors and nutrients of the ingredients. Wet grinders come in various capacities and are an essential tool for households and restaurants that prepare traditional Indian foods.
