I Loooove coffee! :)
If I ever come across a recipe that suits your desires I'll let you know. when I am back on my feet I'll be soaping again so I'll keep you in mind. Substituting with a recipe like this one is pretty risky so I don't advise it without using a soap calculator and doing research.
Good to know about substitutions! I expect I would very closely follow recipes, tried and true, for a while once I ever get started.
Tallow and lard soap is supposed to be the best there is. We made lard soap when we raised pigs that one year, it was a bit difficult mentally for me because I am a vegetarian but I was determined that if lives were to be taken on our homestead then there would be absolutely no waste. One day we'll have to get together and do some soaping. Maybe when steem soars!!
Yes!!
