The answer is Cake Batter.

Notice the exit in the foreach loop? We've talked about the exit command a few different times, including the video Checking the Request Method, 2:40-2:50.

I got stuck on this one too. The foreach goes through one time then exits. Took me a bit to concentrate and understand this.
