Funny thing. When I was a kid, my dad wanted to make cold process soap. He had us save all of the kitchen drippings (bacon, ground beef, excess vegetable oil....) in a big coffee can. When it was full, we followed a YouTube video and made soap out of it. Without cleaning the fat or trying to figure out SAP values. I think we used a huge amount of water, too. We mixed the lye in a crunchy plastic container which then warped and almost melted from the heat. We added pink mica from a melt and pour kit that promptly morphed into a pinky brown color. Then we poured in a bunch of ground cinnamon to hopefully make it smell good. (Shocker, it didn't!) It was such a huge batch that I think we cut 30+ bars. They warped so much as they cured that they were u-shaped on top. They didn't lather, and they smelled very much like rancid bacon with gritty cinnamon. And we had to use them for so many months until he got sick of them and bought regular soap again. We never used it all up, and friends we gave it to never asked for more.
Ever since that first batch, the idea of anything "bacon" and "soap" together kinda makes me shudder.
