In a food processor fitted with the S-shaped metal blade, add 500 ml (2 cup) of the flour. Add the egg mixture and process for 30 seconds. The dough should not form a ball but remain lumpy. If the dough seems sticky, add the remaining flour, 15 ml (1 tablespoon) at a time until it brakes into lumps.
Place onto a work surface and press the pieces together. Knead for 1 minute or until the dough is smooth.
