What is the fine-grained topic of the following text: My banana pepper crop this year produced just enough for me to make Sweet and Sour Pepper Relish, a recipe from the good ol' Ball Blue Book (a staple for any canner) and one that i haven't made in years, mostly because a) we haven't had a garden and b) anyone who has tried to can with 3 kids on their feet understands the complexity of the task. Only return the topic.
