Good for you!
I hafta tell ya, I read the pertinent parts of that book
3 times before trying to make LS back in 2004. I even created
a cheat sheet to follow. It was a TOTAL FAIL and I swore I would never make liquid soap again!
A year later, I ran into a liquid soap recipe on MMS that called for water:KOH at
2:1. Success! I then went back to Failor's recipes and analyzed all her water:KOH ratios in them... turned out to be
3:1. Since then, I use 3:1 because of the water loss during the cook.
2:1 also works at times, depending on oils used, but you risk the batch starting to bloat up and over the pot. If that happens, I immediately put the pot in the sink, stir it down and add cold water equal to
3:1. It's exciting to be sure.
