I like the idea of Harry being a good cook, but hating it due to the Dursleys.
Then, thanks to the Weasleys, he slowly discovers the sheer joy of it. Helping Molly in the kitchen, getting to spend time with Ginny while making a meal.
Then, when he and Ginny are married, the two of them cooking together, laughing, sharing jokes, stealing kisses as they prepare a meal.
Then James, Al, and Lily not knowing any other way. All the nieces and nephews loving eating at Uncle Harry and Aunt Ginny’s place, not just for the taste, but for the dinner theater.
