Step #2 Note: the egg white is integral in this drink.
Step #3 It makes it nice & frothy like an Orange Julius.
Step #4 Please don't omit it.
Step #5 Another Note: It has been brought to my attention that you may also use a TB of egg substitute like Egg Beaters or some other pasteurized brand if you are concerned about a raw egg white.
Step #6 I have not tried this but I see no reason why it shouldn't work.
