Your soaps are beautiful! Many years ago when I was first making soaps, I read about putting banana puree in soap. It's highly likely that it was on this site, might have been a general discussion about adding foods, or, a little part of my brain is saying it may have been mentioned in conjunction with a hair soap?, but it's been a looooonnnggg time, so I can't say for sure. Anyways. I had only made a few batches but decided I could do soaps for Christmas presents, and doing a variety meant I got more practice...so...I made up recipes with different combinations of ingredients - five I think - some in individual molds, some in box molds, and planned on putting some of each kind in a gift bag and ask for feedback on them.
I pureed the bananas, I may have mixed some heavy cream into it, and I think I made ice cubes with it. I had some generic soapy-smelling FO I to use up, and I had this yellow colorant left from the batch I turned into maize and blue Ms for my SIL, so I threw some of that in just because, and when it went into the mold, it looked like something you'd find in a baby's diaper. (It hadn't improved any when I cut it either, it was just firmer.) Now, remember, this was supposed to be for Christmas, and I actually considered throwing it out, but that wouldn't get me any feedback on the recipe, so I included them. They had about ten weeks to cure, and when I tried it, it was just meh, nice enough soap, but nothing special. Fast forward three years and I am unpacking my craft room stuff after moving to Southern California. Huh? What's in this box? Hey, it's the samples I kept for myself from those Christmas soaps! Geez, it's been three years, and that yellow one is so fugly, I'm just throwing that one out...no, wait...just try it, remember that forum about soaps improving with age? Yeah. That soap was amazing. The lather was rich and creamy, it left my hands feeling soooo soft, I couldn't believe it was the same stuff! Currently, most of my craft room stuff is stored in the loft of the shed, and I have yet to find my folder with the information on those soaps...
