I used to have a recipe for a dip bait made mostly from shad. The first step was to take a quart jar full of shad, bury it just below the surface, and dig up the liquified stuff a day later. It went on further and promised to catch fish (and melt any plastic it was spilled on). I just got to thinking though: Would this liquified shad work well on a sponge? I am thinking it would.
