While avocado-and-cheese Doritos and Jagarico were on konbini shelves last year, this year¡¯s unlikely savory flavor combination seems to be cheese and mentaiko, which is spicy cod roe.

Calbee has already released limited-edition potato chips (?124) and Jagabee potato sticks (?130) flavored with cheese and spicy fish eggs, but for something a bit more sophisticated, Kameda Seika, after doing a survey with users on recipe website Cookpad, has released a mentai-cheese version of its kaki no tane rice crisps (?108) in partnership with the site.
