The RSVP Endurance Egg Separator uses gravity to separate egg whites and yolks. Simply crack your egg and dump into the spoon. Wide slots on either side of the spoon – too small for the yolk to fit through - suck the egg white away from the yolk. You end up with a perfect, unbroken yolk every time. This spoon features a crimped handle, which allows it to hang off the side of any size bowl.
