In Tokyo yesterday, I bought three packs of Japanese space food at a science museum. Pictured here are a pack of daigaku imo (candied sweet potatoes) and takoyaki (balls of batter with octopus in them). I tried takoyaki, chocolate cake, and pudding. They were all pretty decent, but the pudding — advertised as not too sweet, with a smooth, melting texture — was the only one that I could actually see myself wanting to eat again. For six bucks, though, I think I’ll stick to real food as long as I’m on earth.
