Had to do this post.
A conversation a couple of weeks ago made me want to try this. I added olive oil to our base SD flour. I have to say it is just like paraffin oil with the tiniest hint of, I'm not sure if I want to say olives, but certainly a green vegetable scent.
I am guessing here when I say use it up within a month.
If you want to rescue a very dry snuff just go to your kitchen cabinet and add some light olive oil. Just don't come crying to me two months later saying it is rancid.
