This recipe is by no means set in stone. It's a procedure. Bring your own flavors to the party. You'll be glad you did. I will say, though, that vanilla and black pepper make wonderful additions! If you make this jam to taste, store it in the fridge for up to a month. If you want to can it and keep for months and months, please follow the USDA canning guide to make sure your jam is safe for long-term storage.
