Basque Biscuits

Whisk the butter in your food processor bowl until you get a smooth texture.

Add the brown and caster sugar, whisk until it whitens.

Add the egg yolk, mix.

Beat the egg a few seconds with a fork, pour half of it in the bowl and set aside the other half.

Mix some more.

Finally, pour the flour, ground almond and baking soda.

Mix until homogeneous.

Make a ball, place in a cling film and set aside in your fridge for 2 hours.

Preheat your oven at 180 C / 355 F degrees.

Spread the pastry between two baking sheets, shape with cookie cutters.

Spread with the remaining beaten egg (add milk if you don't have enough).

Make cuts with a fork or knife for decoration.

Cook 10 minutes.

Let cool down on a grid and store in a metal box.
