I have some deer fat that I wanted to try to make some soap out of. It is a VERY dry crumbly fat. What should I add to it? I have alot of olive oil. Would olive oil be a good fat to add to the deer fat? Has anyone ever made deer soap? :haha: I have about 3 cups of it. I rendered the fat, then boiled it will water to clean it twice. It is a nice creamy white color. I am going by the directions in the "Encyclopedia of Country Living", and some off the internet. My grandpa used to make lye soap (at lease his mom did), so I'll likely be asking him some questions too. Some places say to add salt to the fat, but my book never mentions it. Generally, I don't know what I'm doing. :haha: I wanted to make my own lye, but I think I will buy some for my first attempt.
