Madoka is silently contemplating now. Should she maybe ask the train for a month of sweet potato as the main ingredient? But then again, it's so sweet, she's not sure if it'd make for a good main ingredient.. People on the train may get sick of it real quick.

So she drops the idea for now, instead looking over at Tidus for his question.

"You can just bake them and eat them that way.. but usually they're more.. um, a kind of flavour? Like-- the way you have ice cream flavours, like strawberry and chocolate! Where I come from, we have sweet potato flavours for everything too. Ice cream, cake.. all sorts of sweet potato-flavoured snacks!"
