• 300 g flour (10.5 oz)
• 100 g powdered sugar (3.5 oz)
• 200 g cold butter (7 oz)
• 2 egg yolks
• a pinch of salt
• 2 tblsp finely grated orange peel
• + 1 egg yolk
• 1 tblsp milk
• 1 tblsp granulated sugar
• orange marmelade
• apricot jam

1. Sift the flour with salt and sugar on the kneeding board. Add finely grated orange peel and chopped butter.
2. Rub the butter into flour/sugar mixture with the tips of your fingers creating crumbs.
3. Add yolks and mix everything quickly, kneeding slightly to get smooth dough. Form a ball, cover with plastic foil and chill in the fridge for 1/2 hour.
4. Roll it out between two sheets of baking paper to 2 mm thick.
5. Use either flower or heart shaped cookie cutter in two different sizes (or use a plain, small round cutter for "holes").
6. Cut the biscuit and place on a baking tin covered with baking paper. Make a "hole" in half of the biscuits with a small cutter. Collect the leftovers, form a ball again and chill before rolling it out and cutting more biscuits. Repeat until you have used it all.
7. Beat slightly an egg yolk with milk. Brush the biscuits with yolk/milk and sprinkle with granulated sugar.
8. Bake for 10-12 mins at 175°C (350F).
9. Leave the biscuits to cool on a wire rack.
10. Spread a teaspoon of orange marmelade on a whole biscuit and cover with the second biscuit (with a hole).
11. Warm 2 tblsp of apricot jam with 2 tblsp of water (or orange juice) and fill the holes on the finished biscuits.

These are the second favourite biscuits at my home. I've been making them for about 10-11 years now, and never found anyone who didn't like them. Found the recipe long time ago in a magazine.
