By request, but modified to "foods that sound gross but are delicious"
  1. Trippa alla Romana
    It's tripe, but it's Roman
  2. Shiokara
    Japanese salt-cured squid ofal
  3. Hungarian calf's brains and eggs
    Maybe it should be calves' brain if you're really hungry
  4. Szechuan pork kidneys
    Also try Szechuan pork lung
  5. Ris de Veau de Lait à l'Ancienne
    Doesn't that sound yummier than "French style veal pancreas gland"?
