Knock out the pomegranate seeds with a spoon, catching the juice. Mix the pomegranate seeds and juice, cranberry juice, orange juice and lime juice.
Add 3-4 ice cubes or crushed ice to each glass. Add 2 cl vodka and 2 cl Cointreau to each glass. Spread the cranberry juice mixture over them and top up with 100 ml mineral water each. Decorate as desired with mint leaves.
