I have looked into doing this via my local farmers market and they required we have a food license for packing foods, which also includes having someone come out and inspect our kitchen we use to prepare food. It was a bit more of a process than we were interested in, but I think each farmers market has their own regulations for those types of products. I jar and sell our sauce, on a small scale, via word of mouth from family and friends. It's not much, but it does bring in a little extra cash in the BBQ season.
