1. Add lemon juice, fresh blueberries, and pomegranate seeds to a cocktail shaker and muddle.
2. Add ice, Bacardi, blueberry simple syrup, and Triple Sec, and shake vigorously until well chilled.
3. Strain using a fine mesh strainer into your glass. Add ice if preferred.
4. To garnish, add a lemon wheel slice to pick and lay pomegranate seeds inside wheel.

For the blueberry simple syrup:

1. In a small saucepan, bring water and sugar to a boil, stirring until the sugar is dissolved.
2. Add blueberries and a tiny pinch of salt to the saucepan and stir to coat the blueberries.
3. Turn the heat to medium-low. Allow the berries to simmer on low for about 10 minutes. Do not stir them during the simmering.
4. Remove the saucepan from the heat and allow the berries and syrup to cool completely to room temperature.
5. Once cool, strain using a fine mesh strainer into a container. Do not press on the berries while straining.
6. Refrigerate. The syrup will last up to 2 weeks, as is, in the refrigerator, or if you add a tablespoon of vodka or rum, it will last longer.
