The garnishes are almost as important as the drink in this festive Tiki cocktail for two. Traditionally, this is served in a large bowl-like vessel called a "scorpion bowl" or a "fish bowl," but can also just be served in a pitcher and divided into smaller glasses.
Working in batches in a blender, combine all the ingredients along with ice, until the ingredients are fully incorporated and ice is crushed. Transfer to a scorpion bowl-style drinking vessel or a pitcher. Garnish as desired and serve immediately.
