BTW, Murray, what did you expect to gain by putting the supernatant liquid back in the pot? That contains all the garbage that was leached out of the good stuff. Reminds me of my daughter's idea for saving gasoline. She thought of putting a windmill atop her car driving a generator which would drive an electric motor to assist the gasoline engine.
