Fill a cocktail glass with ice (a Collins glass works well or a tiki mug if you have).
Pour the white rum, gin, brandy, orange juice, lemon juice and orgeat syrup over the ice and stir well.
Float the sherry on top by slowly pouring it over an upside down spoon into the drink.
Garnish with the mint sprig and serve immediately.
Notes
Orgeat is an almond-flavored simple syrup. If you can't find it in the grocery store or make it at home, some of the best substitutions would be almond extract with regular simple syrup or amaretto liqueur (these would be the best options to keep the nuttiness).
If you have a cocktail shaker, feel free to use it. Otherwise, simply add the ingredients straight to the glass filled with ice.
Keep your glassware in the freezer beforehand to keep the cocktail chilled for longer!
The Fog Cutter traditionally comes in a fog cutter mug. It is a ceramic mug created by the same person who created the drink, Victor “Trader Vic” Bergeron, in the early 1940s. The mug is painted with images of hula girls, tropical fruit, or a tiki, hence why it is considered a tiki mug. It comes in different designs but is usually tall, thin and narrows in the center.
