<<Disclaimer: Verify this information before applying it to your situation.>> Hi, I am wondering if the problem with the Skippy was a contamination one. Do yall use a dedicated gf jar? I try to have my own jam, margarine, p butter, Mayo etc. Or I know I am risking all sorts of crumbs from others' knives contaminating the jar. Might be obvious to most but, hey, in 7 years in never occurred to me to check out my lipstick.... Shellie
