Let's assume we have some substantial chunks of kidney fat, etc., from a freshly-killed pig. We want to make rendered lard for soapmaking and/or cooking. I have seen at least three techniques: 1) Melt lard in large pot, skimming away all membranes, tissue, etc. and strain through several layers of cheesecloth. 2) boil fat in an equal amount of water until melted, then add another equal amount of water into the kettle, allow the entire mix to cool, and skim the fat off. 3)melt lard in a slow oven, then ladle into a bucket filled with cool water, then skim off fat as it coagulates on the surface of the water What is your technique? Are any of these sufficient? I want the cleanest, purest lard I can make, and all of the techniques involving water scare me because I fear the excess water left after skimming might affect my soap recipes. Any suggestions?
