Place butter, caster sugar and Fate low protein all-purpose mix into a bowl.
Mix and knead until it binds together (add water as needed to form a manageable dough).
Transfer to a surface lightly dusted with Fate Low Protein All-Purpose Mix, and continue to knead dough until smooth.
Roll dough to a thickness of ½ a centimetre, cut into 12 pieces (using a small cutter mould) and place onto a lightly greased baking tray.
Cook for 20-25 minutes, until golden in colour.
Remove from oven and cool on wire rack.
