Put semolina in a bowl. Add butter, baking powder, cinnamon, salt and 1 tablespoon lemon juice and knead. Knead the yoghurt. Put the dough on a baking tray lined with baking paper and smooth it down. Use a sharp knife to mark diamonds of approx. 5x5 cm. Press a pine nut into the middle of each diamond.
Bake the cake in a preheated oven (electric: 175 °C/ gas: level 2) for 30 minutes. Remove from the oven and cut the marked lozenges. Continue baking for about 30 minutes. Mix sugar beet syrup, remaining lemon juice and fine orange fruit. Brush the lozenges several times with the mixture and leave to dry. Results in about 40 pieces
