That way, you scrape all the ingredients off the side of the mixing bowl. With most Bosch stand mixers, various attachments are included. So you can cut, grate, and blend ingredients with the stand mixer. you can easily adjust the speed of a Bosch stand mixer via the dial at the front of the mixer.
