Combine the flour, sugar, baking powder, and salt in a large bowl. Mix well. Add the olive oil and ouzo (or orange juice) to the dry ingredients. Knead until you have a smooth dough. If the dough is too dry, add a little water.

Wrap the dough in plastic wrap and let it rest for about 30 minutes.

While it rests, prepare the filling. In a bowl, mix the chopped nuts, figs, dates, sugar, cinnamon, honey, and citrus zest. If the mixture is too dry, add a few tablespoons of water to moisten it.

Preheat your oven to 350F/177C.

Roll out the dough on a floured surface to about 1/8-inch thickness. Cut it into circles using a cookie cutter or a glass about 3-4 inches diameter (7.5 to 10 centimetres).

Place a spoonful of filling in the centre of each circle. Place a second circle over the filling and seal the edges by pressing with a fork or your fingers.

Arrange the skaltsounia on a baking sheet lined with parchment paper. Bake for about 20-25 minutes or until golden brown. Once cooled, dust with powdered sugar for an extra festive touch.
