The creamy center is then enrobed in dark chocolate and topped off with a southern pecan.

The most common variation for home cooked recipes is regional to the southern United States and incorporates crushed cookies, corn syrup, chopped pecans, and bourbon into a mixture that is formed into balls and coated in powdered sugar to prevent the evaporation of the alcohol.

Once molded they are aged for up to a week in a sealed container in a cool dark place before serving.

They will stay edible for up to a month before becoming too frail to pick up in one piece as the evaporation process desiccates the packed structure of the cookie.

The filling can also be similar to a truffle or a cherry cordial, with added bourbon.
