Thank you guys for the suggestions. I, however, have a question concerning the use of animal fat/oil compared to plant fat/oil. Since animal fat becomes "rancid" (degrades) in a shorter period of time than plant fat, does anyone have an idea of "shelf life" when using animal fat? I ask because, the patches I had (borebutter, thus crisco/plant fat) still worked 7 yrs after I purchased them; my wife found the reciept last night. She saves EVERY reciept.
I really like the olive oil idea...do I use Balsamic or Extra Virgin (bad joke).
