Melt the chocolate over hot (not boiling) water. Add the syrup and bourbon.
Combine and add to chocolate mixture, mixing well. Let stand 30 minutes. Form (roll with hands) in 1-inch balls. Roll in powdered sugar. Let "ripen" in covered container at least several days before serving.
For coffee flavor rather than chocolate, use ¼ cup instant coffee rather than chocolate.
