I offered one butcher a trade and he trimmed up the sebo (the fat around the kidneys, white, dry and crumbly) for me and gave me a ton in exchange for only one bar of pachouly soap. If I were you, I would try for something like that. My second butcher didn’t trim it up, dumped some bones on me and I cut my finger trying to separate out the good fat from membranes and embedded glands before rendering. I am going to try to talk to him about trimming t for me and offer him a few pesos for his trouble. Sometimes free is not worth it to me. They put this fat in the trash, you are helping them in a way because they must pay for disposal, so don’t feel bad about it.
