This is my favourite, go to refreshing mojito, which is perfect for the heat wave we are experiencing.
You will need Havanaclub rum, blackberries, lemon, mint, and blackberry bubly sparkling water (optional honey or simple syrup)
Muddle blackberries and mint, shake together juice from half a lemon, four shots of rum with ice. Pour over muddles berries. Top with bubbly, stir and enjoy. (This makes 2 drinks). Optional you can add a teaspoon or simple syrup or honey in shaker but I prefer it little bit more bitter.
