Ice Cream Cones

Mariani (1994) writes as follows about the origins of the ice cream cone:

The ice cream cone is equally as confusing as to its origins. It seems clear that the cone (a wafer rolled to hold a scoop of ice cream) became popular at the 1904 St. Louis World’s Fair, but there are several claims as to just who started hawking it there. Some authorities credit a Syrian immigrant named Ernest A. Hamwi with the invention, which was actually a Persian pastry, zalabia, that Hamwi rolled to hold ice cream when another concessionaire ran out of ice cream dishes.
