I would love some information/research links regarding stuffing my own hot dogs for service. For instance, what equipment do I need? I read somewhere that hot dogs don't have hog casings but rather casing from another animal, sheep I think? What ingredients make a hot dog rather than a frankfurter rather than a bratwurst? How would I cook, hold, and store for service? Prepare in morning or night before? I live very near a meat market so ingredients won't be an issue, just need to know what a hot dog really is. A link to an entire history of hot dogs and it's related sausage friends would be great for this. If you have knowledge, please post it. If you don't have specific knowledge but know where I might find some, a link is just as helpful. Thank you so much.
