Different countries have different standards to determine the safety of foods. Most government health organizations quickly ban foods that pose potential health risks. But there is an entirely separate category of cuisine that falls into the "gray zone," not necessarily dangerous, but banned for a variety of other reasons. Often, with this controversial fare, what ends up being legal in one country is considered contraband in another. From the reemergence of mind-altering Absinthe in France to gourmet uses of the coca leaf, from Ireland's potent Poitin liquor to a luxurious Foie Gras update to the Chicago-style hot dog, come see how some enticing foods are a lightning rod to both the connoisseurs who savor them and those who feel compelled to protest.
