Next I will show how to make biscuits with the accessory for the mincer. If you don't have it, make it simpler, roll out a 7-8 mm thick dough cake (the dough is a bit hard after the fridge, so in this case it would be better to keep it less cold), and cut with some shapes. (flowers, stars, etc.).
So for the mincer - cut the dough into small and long pieces to fit in the machine.
