As you can see, the blender had no problem tossing around the dough and mixing it in very little time. I used the ingredients for pizza dough that were included in the book they included. As they mentioned in their infomercial, the process was a lot quicker than using the KitchenAide mixer. However, with the Ninja, I had dough wrapped around the dough hook and the dough was not in a ball, like it is when I make it in the KitchenAide mixer.
That being said, the mixing process is so much faster that I was done with the entire process long before I would have been with the mixer. Also, their instructions call for 1 hour to wait for the dough to rise, which was much faster than the ingredients I have been using with the KitchenAide.
I heated the Big Green Egg up to 600-700 degrees and popped on the pizza with the parchment paper. I usually let it cook for 3 or so minutes and pull the paper off the grill once the dough is cooked a bit.
Personally, I was happy with the results of the dough and especially the speed of the Ninja. While I did have the one bubble, the pizza was made quickly and tasted great. I can envision using the Ninja more often with dough than the KitchenAide simply because of the time it takes to make it. Also, clean up was a breeze, I soaked the bowl and the dough hook in the sink for a while, poured out anything that dislodged, and put them in the dishwasher. No troubles.
