1. Add the dates to a blender/food processor and chop coarsely, add the ground almonds, hazelnuts, and cocoa and blend until everything has turned into fine crumbs. Add the warm water and mix again briefly until the dough comes together. Shape into a log and cut into 20 slices. Shape each slice with wet hands into a ball and then into an egg. Roll the eggs in the chopped pistachios, walnuts, coconut flakes, or cocoa powder. Store in a tin box in a cool place.
