I always headcanoned that Zed has a sweet tooth. I imagine he would like simple sweets, Things like merengue cookies and mochi. Contemporary candies I think he would like are plain m&m's and kit kats.

Kayn, I don't think would like sweets, but he would love spicy food, making a show of dumping hot sauce in his soup. He would eat shit like hot cheetoes and takis.

Neither of them enjoy rasins.
