This one is controversial. Most authorities are split between gin (8, 115, 228, 234, 251, 254, 299, 301) and chewing tobacco. (21, 98, 147, 149, 286). Green (145) ventures that it is rum-soaked chewing tobacco. Gilbert, in his Bab Ballad “The King of Canoodle-Dum” (127), tells of a cannibal king who orders that “every lady, and every lady’s lord should masticate jacky (a kind of tobaccy), and scatter its juices abroad.” All this leads me to conclude that Buttercup’s jacky is most likely chewing tobacco soaked in gin or rum.
