A pasta machine is a kitchen appliance designed to roll and cut fresh pasta dough into various shapes and thicknesses. It typically consists of two rollers that flatten the dough and a set of attachments for cutting it into noodles like fettuccine or spaghetti. Using a pasta machine allows for more consistent thickness and texture compared to rolling by hand. Many models are manual, requiring a hand crank, while others are electric for easier operation. This tool is popular among home cooks and professional chefs alike, enhancing the quality of homemade pasta dishes.
