Here is my Bosch Universal Plus with 1750 grams of King Arthur Bread Flour. It did a great job. It may appear that the dough is just spinning but it is actually kneeding like a saltwater taffee machine. I had to stop and start it to see it working with my own two eyes.
Here is a video of my new Bosch mixer. It is mixing a 1500 gram batch of Caputo Tipo 00 pizza dough. This mixer is awesome! Next time I will try a 2000 gram batch.
