etymonline
taffy (n.)
coarse candy made from sugar or molasses boiled down and cooled, 1817, related to toffee, but of uncertain origin; perhaps associated with tafia (1763), a rum-like alcoholic liquor distilled from molasses, presumably of West Indian or Malay (Austronesian) origin (perhaps a Creole shortening of ratafia). On this theory, the candy would have been made from the syrup skimmed off the liquor during distillation.
