In a cocktail shaker, combine all the ingredients together over ice and shake well. At least 30 seconds.
Double strain back into the shaker cup and remove the ice. Shake the cocktail now "dry" (without ice) for at least 1 minute. If your arms aren't sore you didn't do it right...
Slowly pour the cocktail into a Collins glass and rest 45-60 seconds. Then carefully top the drink off with 2 oz. of club soda down the center of the drink. The head of the egg foam should rise and go about 1/4 inch above the rim.
Garnish with orange blossom water over the egg white, a orange wheel and flowers if desired.
Try a traditional gin fizz by swapping out the fresh orange juice for lime juice instead.
