Sure there are all sorts of edible flowers but have you actually eaten them? I have, they taste like, well, like flowers. Wouldn't you rather eat something that looked like a flower but tasted sweet? Of course you would.
I'm sure for some people you could draw a comparison between the power of cake addiction vs. Katamari Damacy addiction. Both are sweet, colorful, fun and dangerous in large doses. I want a lego and a flower!
I love a good culinary "gotcha" every now and again. This one is especially well executed with the matching saucer and the doily and the little floating marshmallows. I know I'd be fooled and delighted!
