Caramelized Potato Kit Kat. A product of Japan. Purchased from Jappy11 on Ebay.
Allegedly caramelized potato. The package shows pan-fried potatoes with what I guess are black sesame seeds, but I didn't get any flavor other than white chocolate and sugar wafer. I'm a supertaster, so if there were any bit of the advertised flavor there, I should have caught it. Maybe someone at the ol' factory missed this one.
