Japanese Kit-Kats

They come in 200 flavors that you wouldn't even think of with new ones as specials all the time. And there's a type that you bake. Briefly. In a toaster oven. And you must stand there and watch them or they will will burn in five seconds.

These get poor reviews on Amazon because people were expecting full size, not mini Halloween size, and they're expense so not a good candy value.

There are other options. Full-size packages with less variety.

Green Tea
Matcha
Sake
Strawberry
Strawberry Cheesecake
Cookie and Cream
Azuki Bean
Purple Sweet Potato
Melon
