Food processors and blenders are not one in the same, as blenders require some sort of liquid to keep food moving through the blades. Food processors, on the other hand, have a flat bottom and thus do not need additional liquid.

This can be a great way to easily improve food quality and customer satisfaction. There comes a point, however, when refusing to use kitchen machinery becomes tedious and takes homemade just a bit to far.
