- Step 1
Use an electric mixer to beat the butter and sugar in a medium bowl until pale and creamy. Add egg yolks, one at a time, beating well after each addition until just combined. Add flour, cinnamon, cardamom and cloves, and stir to combine.
- Step 2
Shape dough into a disc and cover with plastic wrap. Place in the fridge for 1 hour.
- Step 3
Preheat oven to 180°C. Line two oven trays with baking paper. Roll out dough between two sheets of plastic wrap to a 5mm-thick disc. (If dough is quite soft refrigerate for 30 minutes.) Use a 7mm-diameter star-shaped cutter to cut out biscuits and place on lined trays. Bake, swapping trays halfway through cooking, for 10-12 minutes or until lightly browned. Remove from oven and set aside on trays for 10 minutes to cool before transferring to wire racks to cool completely.
- Step 4
Combine the eggwhite and brandy in a medium bowl. Gradually whisk in enough sifted icing sugar to make a thin glaze. Brush biscuits with glaze, decorate with cachous if desired, then place on a wire rack to set. Store in an airtight container between layers of paper towel.
