Maybe this has been discussed before and I missed that class! This has probably already been figured out by now I would imagine.. If so I apologize haha! I needed to keep 4 different rubs on 4 different half-racks of pork ribs separate for the purpose of "testing" new potential experimental recipes... after a short conversation (with myself - lol) I came up with this... Toothpick's marked by a Sharpie (ink pen)! Simple. Available. Quick. Inexpensive. Disposable...Item #1 got a single stripe, #2 got a pair of stripes, ect.
