Duff is a Bahamian cuisine dessert dish made with fruit (especially guava) in a dough.
[1] Fruit is folded into the dough and boiled, then served with a sauce.
Ingredients include fruit, butter, sugar, eggs, nutmeg, cinnamon, cloves, flour, rum, pepper, and baking powder.
Duff is also an English term for pudding.
[2] In the 1901 short story by Henry Lawson, "The Ghosts of Many Christmases", published in Children of the Bush,[3] plum pudding is referred to both as pudding and duff: The storekeeper had sent them an unbroken case of canned plum pudding, and probably by this time he was wondering what had become of that blanky case of duff.
