In a cocktail shaker add the mint, pomegranates, strawberries and sugar then muddle well. Add ice and the rum and shake vigorously. Strain the cocktail into an ice-filled glass. You might have to take the lid off of the cocktail shaker and pour the juice out holding back the fruit. Once the glass is filled, top it off with a small amount of club soda. Give it a little stir and then garnish with a sprig of mint, a strawberry and a few pomegranate seeds. Enjoy and happy Labor Day!
