Add all ingredients into a cocktail shaker, cover, and shake for 15-20 seconds to allow ice to make the ingredients cold without watering it down.
Pour straight up into a martini glass.
Notes
If you do not have a cocktail shaker, you can use a tall glass with ice and stir vigorously. Use a strainer to pour cocktail into martini glasses to hold ice back.If desired, you can use super fine sugar to rim the glass before pouring the cocktail in.
