Your Breton biscuit dough is ready. Weigh out into pieces of about 12 oz (325 g). Flatten into cakes and wrap in plastic film. Refrigerate overnight before using.
Remarks
If you simply want to make Breton sablé biscuits, roll out the dough next day to just under half an inch (1 cm) thick and cut out to the size and shape of your choice. Bake at 360°F (180°C) for about 25 minutes.
