 A dessert called Waldorf pudding was served to first class passengers on the RMS "Titanic" on the April 14, 1912.The exact recipe for this dessert remains unknown and it may have been specific to White Star Line.Several speculated recipes using apples, walnuts, and raisins (which are the key ingredients of Waldorf salad) exist but there is no evidence that any of these ingredients were used in the Waldorf pudding served on the "Titanic".
