Here is my process. I use 1/2 water and 1/2 canned milk. (Make sure it is not sweetened milk!) When I use soapcalc, I up my water from 38% to 40%. I put my can of milk in the freezer to chill. This may not actually be necessary, but when I did this my soap came out great, so I have superstitiously stuck with it. I mix my lye with my water, then melt my oils. When the oils and lye water are between 95 and 100 degrees F, I add my milk to my oils, stir, then pour my lye into my oils. This way I consistently get milk soap that doesn't smell like baby vomit.
