An Old Saying. . .

In professional kitchens there is a saying, "garbage in, garbage out" which implies that a finished product is only as good as the quality of the ingredients that you put in it.  Particularly for stock bases, which tend to be giant vats of meat bones and the flotsam and jetsam of kitchen cuttings, root ends of vegetables, skins and such.

After I followed this garbage truck down a winding county road for ten miles last Saturday, watching the chap in the back nearly bounce out a dozen times like a ping pong ball, I kept hearing "garbage in, garbage out" in my head. 

Secretly, I was wishing the guy would bounce out just as a lesson to him and the damned fool who was tailgating right on the bumper of the garbage truck the whole time.
