Thanks for the link. It appears to be very simple, using only three ingredients: coconut oil, lye, and water, provided coconut oil can be had during the hard times. She also slammed the use of lye as dangerous, but then used it in her formula. When growing up on the farm (back in the 50’s), we used lye and livestock fat. Worked great. Plus boiling off the fat resulted in these crispy crinkles that were to die for. Literally! :-)
I think coconut oil would be pretty difficult to come by. The better option would be to go ahead and make the soap and store it away for later use. Coconut oil should make a nice hard bar, as opposed to say olive oil, so a batch should last a good long time.
I didn’t take it so much as her slamming lye as just making sure people understand that it can be dangerous. Though why you wouldn’t know that I have no idea. I guess the alternative could be to make your own ash, but then the ratios change. But, I suppose that lye would get hard to come by also, so would be good to have that knowledge and skill.
