Here is one I found 2 oz Gin 1 oz Simple Syrup 3/4 oz fresh Lime Juice 3 - 4 oz Soda Water 2 Mint sprigs 2 pieces Limes Muddle one sprig of mint with the lime pieces, lime juice, and simple syrup in the bottom of a bar glass. Add gin and shake well. Pour into a goblet over crushed ice and stir until the outer-glass frosts. Top with soda water, garnish with remaining sprig of mint, and serve. I want to be able to make the syrup with the lime and mint and store it, any ideas?
