OLD-FASHIONED IRISH POTATO CANDY
1/2 (or 1 small) boiled potato
2 cups powdered sugar
1/2 cup peanut butter
Mash potato and enough powdered sugar to make a slightly stiff dough. Roll out dough (on wax paper dusted with powdered sugar) and spread on the peanut butter. Roll dough up (as for jellyroll) to make a log. Chill. Cut into pieces, let air dry for about an hour. Store in airtight container. Makes about 2 dozen confections.
