Combine all ingredients in a shaker. Add ice cubes until the liquid is covered.
Shake vigorously until shaker is cold. Strain into collins glass over ice. Garnish as desired.
Notes
This is a slight variation on the classic Mai Tai. We omitted the simple syrup, if you want to add simple syrup - use ¼ ounce. Orgeat syrup - use store bought or make your own - homemade orgeat syrup.
