I only do HP in the crockpot. I add silk and sugar to the lye water, and since adding silk, I find the soap is a little easier to mold, and the lather is incredible. I just cook mine to the stage that looks like applesauce (or translucent). I don't stir while it is cooking. Then I stir it really well and it looks like mashed potatoes. I read somewhere that when you stir it, if it sticks to the spoon, it is done. Then I add all my goodies and spoon it in the mold and bang it on the floor till it smooths into the corners. The tops are rough, but I use a log mold and when I cut it the top just looks textured. HTH. Dorothy
