[Bapopik at AOL.COM]

   Mrs. Jansson?
   A national dish of Sweden, this was popularized by the Swedish Pavilion during the 1964 New York World's Fair.  Not in OED or Merriam-Webster.


   14 August 1964, NEW YORK TIMES, "Dining at the Fair" by Craig Claiborne, pg. 31:
   With minor reservations, that pavilion's smorgasbord cannot be faulted from fish to frestelse (Jansson's Temptation), but of all the foods the herring is extraordinary.
