Dave:
Generally one taints the meat first, then adds the preservative and ingredients and lets them age in a cool dark place until trapping season. However, there is no set rule about the procedure, one may add the ingredients first while the meat is tainting. Generally one will get a different odor doing it that way but it doesn't mean it isn't a good odor. Actually, when one adds any ingredients such as castor to a meat bait base, they now have a lure. If lures didn't generally produce better results than plain bait, commercial lure makers would have never come into existance and thrived year after year for scores of years. My opinion, the more ingredients in the mix the better as it generally adds more enticement to the animal and keeps the animal at the set longer once they have accepted.
