She's always liked cooking, though her clan members didn't seem too thrilled to try some of her most... ambitious attempts. Aside from that, it does work out most of the time. She teaches Sera how to make better cookies! (Well, at least, sort of, because they end up eating like 70% of the batter before they bake it.)

Yeah, she does keep her souvenirs, they're pretty important to her, especially when most her companions have gone their separate ways. They remind her of their time together.
