In a separate bowl, mix the the rest of the cookie ingredients- sifted flour, semolina, baking powder, chopped pistachios, cardamom.
Whisk the butter and sugar until well combined and slightly fluffy.
Stir in the flour mixture and gather together into a ball. You may have to form it into a ball by hand.
Flatten the ball into a disc and place in cling wrap in the fridge for 30 minutes.
Roll out the disc between 2 pieces of wax/baking paper until it is approximately 8 mm thick.
Cut out circles which are approximately 4-5 cm in diameter. (You can make the circles bigger or smaller as per your preference).
Place the circles on a baking tray lined with a silicone baking mat (use baking paper if you don't have a mat) and bake for 15-16 minutes at 180°C until lightly golden.
Remove from the oven and allow to cool on a rack.
For the decorations
Melt the white chocolate (according to manufacturer's instructions). We melt white chocolate in the microwave.
Dip the cooled cookies a third of the way into the melted chocolate (see note below).
Sprinkle on the chopped pistachios, chopped candied orange peel and a few saffron strands.
Place the cookie on a cooling rack and allow the white chocolate to completely set.
Notes
Keep the melted chocolate in a bowl placed over another bowl of hot water. This will keep the chocolate melted. Take care not to allow water into the melted chocolate.
