Bake or microwave the potato until a fork pierces it easily.
While the potato is cooking, grind the dates, figs, and raisins in a
food mill or chop finely in a food processor.
While the
potato is still warm, scoop out the contents. Mash well.
Mix in vanilla, maple or almond extract, and 5 2/3 cups
powdered sugar until you have a stiff, workable dough.
Add the fruit and mix well.
Refrigerate for an hour or so. Then shape into rolls 1 inch to
1 1/2 inches in diameter. Roll in 1/2 cup powdered sugar and
ground nuts. roll up in plastic wrap and refrigerate. Let
set a day or two, then slice into desired-size pieces.
Store in refrigerator; bring to room temperature to serve.
Keep pieces covered or they will dry out quickly.
Instead of long rolls, the candy may be shaped into bonbon
pieces or used to stuff dried fruits.
