In a large bowl combine flour with sugar, almonds, cocoa powder, and salt.
Incorporate chilled butter into the flour mixture, using a pastry blender, a fork, or a pastry processor, until crumbs are formed. Add water and stir until incorporated.
Wrap it with plastic, shape it into a disk, and refrigerate for at least 30 minutes.
Roll the dough between two pieces of parchment paper or plastic wrap until it's about ¼ inch (6mm) thick.
Use a 3-inch (7.5 cm) round cutter to cut into a disk. Remove the excess dough.
Transfer the cookies onto a parchment paper-lined baking sheet. Refrigerate the dough for about 30 minutes before baking if time allows.
Preheat the oven to 350F (180C).
Bake for 8-9 minutes. Let cool for a few minutes on the baking sheet. Transfer to a cooling rack to cool completely.
