- In the bottom of your glass, add 10 blackberries, rosemary, lemon juice and your choice of sweetener. Muddle all of the ingredients together, squishing everything to release the juices.
- After all of that is combined, add the tequila or vodka of your choice and orange bitters.
- Add ice to your glass, pour your bubbly water over, and gently stir to combine everything together. If you don't like all of the chunks of blackberries at the bottom, you can strain the juice out and just use that if it better suits your taste.
- Garnish with a fresh sprig of rosemary and some fresh blackberries on top. Enjoy!
