Sirius explains to Hope how, lost and broken after leaving home, Sirius had taken to wandering around and watching the Potters as they interacted together. He had noticed Euphemia had cooked for the family every day, something his mother would never have been caught dead doing—he was barely certain Walburga Black knew what a kitchen was, much less where it was in her house—and, curious, Sirius had asked Mum to teach him. She had, gladly, and then when James complained that he was bored and that cooking was women’s work, she had roped her son into learning as well, somehow managing to teach both how to make a meal and not to be a sexist pig. James had never been a brilliant cook, and Lily had, but he made sure to prepare food for them as often as she did after they married. As two men who were each respectively as good (or not) at cooking as Lily and James, this arrangement had amused Sirius and Remus to no end, because Remus had rarely turned on the stove except to make eggs, while Sirius had regularly turned out multi-course meals.
