I don't have a source for these so I can't say if they're candy or cakes or what but I do know they're not fish. Any guesses as to what is hidden inside?
At first I thought this looked like the world's fanciest doorstop or something but then I started drooling and realized that my brain knew it was awesome food so why couldn't the rest of me figure it out? The only way to eat such a fancy dessert is in the tiniest nibbles possible. You have to be careful not to compromise the structural integrity of the stack.
