Do yall have a recipe for buttermilk your willing to share? I have been meaning to ask if the 10 1/2"X 8 3/4"X 3 1/2" deep would be the right size to hold the goat milk batch I want to do first. Forgive me if I am asking dumb ??'s Would I need one, two, three....or how many do yall think. Hubby has an 8' 1X4. I went to the library Friday and they have no books on soapmaking other than pour & melt.
