Take your jack mac, add to it enough of some floating catfish food enough to make it so you can shape it enough to handle. Add a couple cups of salt or sodium benzoate so it doesnt freeze. I would make this just before season, as it will mold up if you make it too far ahead. Theres things you can add to prohibit mold growth but those are a bit expensive.

If you want to spice it up, get some predator bait solutions, ot add some smokes clams, or a few drops of Smoke OIL(not liquid smoke) or some other flavorings.
