This is a tasty filled cookie in a cake-like pastry. The filling is mostly figs, with some nuts and raisins, chocolate and cinnamon. The cookies are filled, then cut and formed into X shapes before baking.
In a medium bowl, stir together the flour, sugar, baking powder, and salt. Cut in butter using a pastry blender, or pinching between your fingers. Add egg, and mix until a dough forms. It may take a couple of minutes of mixing. When the dough starts to hold together, turn it out onto a floured surface and knead briefly. Shape dough into a long roll, wrap, and set aside.
Place the figs, almonds, apricot preserves, raisins, orange peel, chocolate, rum, and cinnamon into a food processor or blender. Process until finely chopped. If the fruit is hard, it may be soaked in boiling water to soften for 15 minutes before processing.
Preheat the oven to 175 degrees C (350 degrees F). In a small bowl, mix together the remaining egg and milk to make an egg wash.
Divide dough into 12 pieces. On a lightly floured surface, roll each piece out into a 8x30cm rectangle. Brush the strips of dough lightly with egg wash. Place a strip of the fruit mixture lengthwise down the center of each piece of dough, and fold the edges over. Roll gently to seal. This will make the filled tube of dough a little bit longer. Cut each tube into 8cm pieces. Make a 2.5cm long slit with a knife down the center of each cut end. Spread the ends out to form an X shape. Place cookies 5cm apart onto lightly greased cookie trays.
Bake for 15 to 20 minutes in the preheated oven, or until the edges are golden. Allow cookies to cool on the tray for at least 5 minutes, so they will not be too delicate, before removing to wire racks to cool completely. Dust with icing sugar when cool.
