Mix all ingredients except for the chocolate chips and wax.
Stir well and add more powdered sugar or cornstarch if it''s still too goopy to handle. Chill for at least an hour. Roll into 1-inch balls and freeze.
Melt the chocolate and wax in a double boiler over low heat. After the balls have been in the freezer for a few hours, remove and dip in the chocolate.
Dip using a fork, shaking as you take them out, and place on waxed paper or parchment to cool. Quickly press a curl of orange zest on the top.
These will last for weeks in the freezer, tightly sealed.
