This video from Harvest Eating, a website devoted to eating seasonally, uses a store bought Panettone to create a homemade bread pudding for the holiday season. The Panettone used comes from Whole Foods, and the rest of the ingredients are easy enough to buy organically if you choose.
I’d like to make one suggestion, though. The Panettone in the box is wrapped in a plastic bag and then in a paper wrapper. In the video, the plastic bag is quickly cut off. Don’t do that. It looks like a useful plastic bag that if opened carefully could be used one more time before hitting the trash.
