In a food processor with the blade, add flour, butter, salt and 5-spice. Pulse until butter ends up in very small pieces. Add the egg mixture and pulse until a ball is formed. If ball is too dry, add a little water or, if too wet, add a little flour. In either case, pulse to incorporate. Wrap ball in plastic and refrigerate for 1 hour. Roll out dough to 1/4-inch thick and dock dough (make small holes). Cut out circles or squares and place on an upside down muffin pan.
