Bring cranberry juice to boil in a saucepan over high heat. Cook uncovered for 10 minutes or until reduced by two thirds. Remove from heat and let cool for thirty minutes.
Combine cranberry juice, Mandarin Liqueur and Lime Schnapps in a small jug. Place a sugar cube in each serving glass. Pour cranberry mixture over sugar, and top up with pink sparkling.
Pour the Lime Schnapps into a highball glass filled with ice cubes. Fill with cola, and serve.
Shake ingredients over ice. Strain into a chilled martini glass. Garnish with a strawberry slice.
