Active in Modica since 1880, it is Sicily's oldest chocolate factory still in production, keeper of the cold-processing method of Mesoamerican origin that leaves Modica chocolate free of added cocoa butter. The Fattojo Experience tour guides visitors through the historic bean-to-bar workshop, from cocoa bean to finished bar, in about half an hour, with a final tasting. The Bonajuto family has carried on traditional recipes and tools for generations, including the antique stone grinder still in use. An experience combining local history with the Aztec cocoa culture that reached Sicily through Spanish rule.
