The craft is a blend rather than a garnish: lean cocoa powder is mixed with limoncello, the liqueur obtained in the traditional way, with alcohol at ninety naturally. That pairing is what the name Cioccolato al limoncello points to, cocoa carrying the citrus spirit instead of sitting beside it.
What draws people in is a particular taste, much appreciated for its marked digestive qualities. After a meal the chocolate does not only sweeten; it offers that distinctive character the liqueur is known for, cocoa and lemon spirit in one small bite.
