Christmas cookies with jam

Steps

• 1. Cut the cold butter into cubes. Mix it with flour, sugar and salt, chop into crumbs (this can be done in a blender or in a stationary mixer).
• 2. Add an egg, continue mixing. When the dough starts to gather into large clumps, stop the mixer and wrap the dough in a cling film. Put it into the refrigerator for several minutes.
• 3. Roll out the dough on a floured surface. Cut out circles. Lay out the cookies on a baking tray covered with a parchment.
• 4. Bake at 170 degrees for about 12 minutes. Shift the cookies on a grill, and let them cool.
• 5. Spread strawberry jam on the half of the cookies with a teaspoon. Cover with the others.
• 6. Optionally sprinkle with powdered sugar.
