Check out this video the cakes just explode into existence!
The cakes are just very slightly sweet, and they dissolve into almost nothing in your mouth, since they are mostly air, though they look solid enough. They're a good snacky food when you want to munch on something without spoiling your appetite (or loading on the calories).
I wish I could get these without driving across town, since I'm always wanting to snack at work. If paper were edible, I'd have the cleanest desk in town. How well do you think this stuff would hold ink?
