How to make
Put all of the products in a large bowl and cut the butter into small cubes.
At first you may think that there is a lot of flour and it will not work out, but do not worry.
Shape the dough into a roll and wrap it in cling film. Leave it for 30 minutes in the refrigerator.
Take out the dough and cut it into 0.6″ (1.5 cm) thick pieces.
Arrange them in a baking tray lined with parchment paper.
Make strips along the butter biscuits, by using a fork and bake for 1 hour at 250°F (120°C).
The baked butter biscuit with wine are sprinkled with powdered sugar.
