Notes
Variations - Japanese Slipper: If you swap the vodka for triple sec, you will make a Japanese Slipper cocktail. Other popular variations are the Amaretto Sour and Whiskey Sour.
Garnish Ideas - Add a maraschino cherry, fresh citrus like limes or a candy cane for the holidays.
Stir - If you don't have a shaker, you can also mix this cocktail with a quick stir. Wait to add the soda until after you've stirred.
Substitutions - If you don't have vodka, you can also use white rum or the spirit of your choice in its place.
Egg Whites - You can add an egg white to the cocktail shaker to create a frothy version of this drink. Some recipes include the egg white, but it's up to you what you prefer.
