The removable lid allows you to add flour or water while mixing without stopping the machine, keeping the process smooth, clean, and efficient. Mix Function with Hand-Kneading Simulation: This baking mixer machine features a removable S-shaped dough blade and "mix-pause-mix" program that mimics real hand kneading, allowing gluten to develop naturally for dough that’s softer, chewier, and more elastic—without overworking like continuous-mix machines, ideal as a sourdough mixer.
