Hey, I have been wanting to use tallow in my soap, and I have some in my fridge, however I rendered it myself. I cannot be sure that I kept it below the temp you are suppost to to render it. I have heard that you want to make sure that you have properly rendered tallow for use in soap. Is this just because of the smell, or something else? If I were to try and use it in a soap batch, would I only risk it smelling bad, or would I risk the soap not turning out right? Thanks!
