You know what eggs are. In cocktails, eggs are used for their foaming properties, giving the drink a rich and creamy texture. The eggs proteins form a 'net' that traps air and liquid extremely well; for this reason, drinks that contain eggs are shaken. They are also used for egg washing, a type of booze washing.
