At the moment I master batch my lye, so can I confirm that if I wanted to replace the additional water with vinegar, I would have to add the additional lye to the master batched lye I have weighed out. Is that correct? Does it mean that using vinegar to replace the water that is not part of the master batched lye, rather than all of the water, that the bar would still be hard? @cmzaha do you use a low superfat because of the vinegar or because you prefer it that way? Do you use distilled vinegar because of the cost compared to ACV or for some other reason?
