Just say - I did half portions. So, let's start. Chocolate grind in a blender into fine crumbs.

On the working surface sift the flour, chocolate and sugar. In the center make a well, add the egg yolks.

Add the soft butter and quickly knead the dough. If the dough will not vmeshivatsya, you can add 1-2 teaspoons of water. Wrap the dough in cling film and put into the refrigerator for 1 hour. To save time, I cleaned for 30 minutes in the freezer. While the dough is cooled, we clean pistachios. Seeds pour boiling water for 1-2 minutes, then drain off the boiling water and pour the pistachios in cold water. Clean them from the husk. Grind the pistachios in a blender.

Take the dough out of the fridge. It should be divided into 30 parts. I got 15 because I was doing half a serving.

Now each piece to flatten with your fingers or roll out with a rolling pin, it all depends on your imagination. The thickness of the pastry should be about 5 mm. To one egg yolk add 1 tablespoon of water, brush the biscuits, sprinkle with chopped pistachios. Bake in a preheated 160 degree oven for 10-15 minutes.

Pour a Cup of coffee and enjoy...
