My aunt Frances would always make these wonderful peanut butter balls during the holidays.
Mix margarine, peanut butter, and sugar. Shape into small balls and place on wax paper. Put a toothpick into each one and refrigerate at least 45 minutes to an hour.
Next, melt paraffin and chocolate in top of a double broiler. Dip the balls, remove the toothpicks, and refrigerate. Don't let the balls touch each other until after the chocolate/paraffin mixture has hardened.
