i know strike king had some a few years back, but probably discontinued it. But this is a tackle building forum so I think making our own should probably be a good topic. I know alot of people think as pork for colder water, but i have always used real pork year round. If you can find the ones that float it always seemed better to me. it was a 50/50 chance for floaters with uncle josh. But if you have any old pork left, add a few drops of glycerin to the jar and maybe a little anise oil. that should keep them fresh.
