Outback Steakhouse® The Wallaby Darned The menu describes the steakhouse chain's popular fruity drink as a: "Down under frozen wonder with peaches, DeKuyper Peachtree Schnapps, champagne, Smirnoff Vodka and secret mixers." While you don't need to use the same brand-name booze as the chain does, you will need to find a can of Kern's peach nectar to re-create the same secret mixer magic. 1 cup frozen sliced peaches 2 ounces champagne 1 ounce peach schnapps 1 ounce vodka 4 ounces (1/2 cup) Kern's peach nectar 2 or 3 ice cubes 1. Combine all of the ingredients in a blender. Blend on high speed for approximately 30 seconds or until ice is completely crushed and the drink is smooth. 2. Pour into a 12-ounce glass and serve with a straw. Makes 1 drink.
