I just recieved my Grandmother's soap making recipe, it is at least 60 years old, hand written in her cook book. This is a direct transcription of it; 3 Parts, (pints?) rainwater in a large stone jar in P.M. , 2 heaping Tbs. powdered Borax, 1/2 cup ammonia, 1 can of lye, (the old lewis lye I presume), stir well let sit til A.M., Add 2 Tbs. Oil of Sasafras, 6 pounds melted fat, not hot, stir until thick as fudge, pour into carton lined with oil paper. So, I like the precision of measurement! I am interested in hearing opinions on the recipe, and anything else related to it. I am going to try this one out in a 1/4 sized batch. My grandmother is 102 this year.
