Amaretto Sour, Improved No. 2

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. Some cocktails use only the egg white (fizzes) and some use the whole egg or only the yolk (flips). There are common non-egg substitutes out there, check out insta-foam
