Obviously, Harry would be one of the main characters as he is the one doing the cooking. Members of the Order like Sirius Black could be main characters too. He might be the one who encourages Harry to cook for the group or gives him some special cooking utensils or ingredients from his family's collection.
One interesting plot could be Harry using his unique magic to create extraordinary dishes for the Order members. Maybe he discovers a way to infuse magic into the food to give them special powers or boosts, like a potion but in a culinary form.
Well, perhaps the plot could involve Harry wanting to show his gratitude to the Weasleys. He might decide to cook their favorite dishes, leading to some comical moments in the kitchen as he tries to figure out the recipes. Maybe he gets some help from the Weasley matriarch or one of the younger Weasleys.
Well, it could be fanfiction where the characters from Harry Potter are involved in cooking in some way. Maybe Harry is in the Hogwarts kitchen trying out new spells on food, or Hermione is using her knowledge to create magical recipes. It's a creative take on the Harry Potter world with a cooking theme.
It's a bit hard to pinpoint the really popular 'harry potter cooks fanfiction' without doing some in - depth searching on fanfiction platforms. However, stories that bring in elements from different parts of the Harry Potter lore and blend them with cooking are likely to be well - liked. For example, a story where the Triwizard Tournament has a cooking - related task. The champions have to use their magical skills and knowledge of different wizarding cuisines to create the best dish. Such stories that offer a fresh and exciting take on the familiar Harry Potter world could be among the popular ones.
The main character is Harry. He drives the story as he decides to cook for the Weasleys. Among the Weasleys, Ron would be a significant character. He could be the one who gives Harry some ideas about what the family likes to eat. Ginny Weasley might also play a role, perhaps she's the first one to taste Harry's cooking and gives him an honest reaction.
One interesting scenario could be Harry trying to cook a traditional wizarding meal but accidentally using muggle cooking techniques. For example, he might try to use a broomstick to stir a cauldron instead of a magic wand. Another could be Harry cooking a special meal for his friends, like a birthday feast, and struggling to get the magical ingredients just right. Maybe he has to deal with a mischievous house - elf who keeps trying to'save' him from cooking by doing it for him in a very unorthodox way.
Another reason could be that Harry sees the Order as being too cautious or old - fashioned in their approach to fighting Voldemort. He might believe that their traditional methods are not enough to defeat Voldemort quickly and effectively, and this lack of progress makes him angry at them.
Maybe he feels that the Order is keeping secrets from him. In many fanfictions, Harry can be a character who values honesty and when he discovers that the Order, which he may consider an ally, is hiding things from him, it can make him angry.
Maybe he has read some really bad Order fanfictions before that were full of inaccuracies. For example, the characters' personalities were completely distorted or the plot was so far - fetched that it made him lose trust in all Order fanfictions.
