I freeze my goat's milk & add the lye to the frozen milk & stir, stir, stir it until the frozen milk is disolved. The fat in the goat milk doesn't carmelize if you keep the lye/milk cool enough. I make my soap in a log mold & gell by covering my mold because too often I had a "bullseye" in the middle of my soap because of a partial gell. The gelled soap gets a bit darker by gelling but at least it's all the same color.
