Pork-flavored postage stamp

The Chinese post office is celebrating the year of the Pig with a pork-scented scratch-and-sniff stamp whose glue tastes of sweet-and-sour pork. Philately will get you nowhere.
When you scratch the front of the stamps, it smells of the popular Chinese dish and when the back of the stamp is licked it tastes of the dish too.
