If you didn't want to make an all goatsmilk batch, you can dissolve the lye in water and add cold condensed goatsmilk after adding the lye water to the oils or at very early trace. My go to recipe calls for 14 oz of total liquid and I dissolve the lye in 8 oz of water and then add 6 oz of cold condensed goatsmilk right after combining the oils and lye water then start stick blending. I like this method a lot because I don't have to freeze the goatsmilk or worry about burning or scorching the milk like when you add lye directly to the goatsmilk. Just wanted to throw that out in case you wanted another option for using the condensed goatsmilk. Good luck! I adore goatsmilk soaps! :-D
