(Got this one on my main account so throwing it over here!)
Arashi isn't much of a cook. She can ensure the meat isn't burned and the veggies aren't undercooked, but she grew up with parents who had very little options or preferences for good food, so she never picked up much of a knack for it.
She's never tried baking before, having never had much of a need for it in her life so far. That may well change once she retires from the whole world-saving business, though. She's got a lot of discovery ahead of her once she hangs up her sword.
