While octopus balls (also known as takoyaki--たこ焼き) are really popular summer snacks, these giant ones known as Bakudanyaki are sold year-round in shops around Tokyo. They have a lot of stuff put into them, from the usual octopus, to a piece of baby corn, a bit of sausage and even mushrooms. You can get lots of different sauces. Usually I get the "cheese mix" which is a variation on a theme, but this time I decided to try the double mentaiko cheese. It was delicious.
