Trying to be thrifty, I made a batch of soap using some of my leftover little of this, little of that, fragrances. Mostly Monkey Farts (which is not all the nice even on its own), Vanilla, and some unidentified floral. Now I have a 10-bar batch of unpleasant smelling soap. So much for being thrifty! Can I re-batch it and add a different fragrance, or will that just take it from bad to worse? Or should I just give away or this whole batch?
