@bigtom13 you just made my day. Memories and nostalgia are such a big deal to me. I am glad that this post triggered some good memories for you.

I am so fascinated by your recollections of this recipe. It sounds so interesting. I've never made soap that way but it would be so neat to try it. I'll do some reading, I have an archive of some vintage ebooks that might have some answers. Maybe your brother can make a copy of it for you so that it's forever backed up for your family. That really is a treasure! (as are your mom's cook books!)

So glad you share this with me. You truly made my day.
