Actually, the batter (or I guess we should form a new term, bat-ough or datter) from my recipe looks like your picture. Sliding the box back and forth on the grates of the type Andy, GG and we have creates the pressure that your scraper does and forces the mixture thru. It's 2 different methods of obtaining the same results, although I'd say yours probably is easier to clean since it doesn't have to be taken apart and the batter cleaned out of the corners and tracks of ours.
Thanks for the explanation MT, as I was having a hard time understanding how it could possibly work well with a thicker "datter"..lol, I like that term.
Another advantage to mine is it somewhat protects you from all the steam of the boiling water. I gave a review of it on Amazon and said the design could be improved however by adding a handle or a nob to the device. Other than that, I love it. I use an oven glove when using it.
