To make blueberry lavender simple syrup, follow these steps:

In a saucepan, combine the blueberries, water, and granulated sugar.

Place the saucepan over medium heat and bring the mixture to a simmer. Stir occasionally to dissolve the sugar.

Once the sugar has dissolved, reduce the heat to low.

Add in the lavender blossoms and let the mixture simmer for about 10-15 minutes, allowing the flavors to infuse.

After simmering, remove the saucepan from the heat and let the mixture cool for a few minutes.

Set a fine-mesh strainer or cheesecloth over a bowl or jar to strain the syrup. Pour the syrup through the strainer, pressing the blueberries and lavender flowers to extract as much liquid as possible. Discard the solids.

Allow the syrup to cool completely, and then transfer it to a bottle or jar for storage.

It can be stored in the refrigerator for up to two weeks.

To make a blueberry lavender mojito drink, follow these steps:

In a cocktail shaker or a sturdy glass, muddle together 3-4 ounces simple syrup and the mint leaves. Use a muddler or the back of a spoon to gently crush and mix the ingredients, releasing their flavors.

Squeeze the juice of one lime into the shaker and add the rum. Stir well to combine.

Fill a glass with ice cubes. Strain the mixture from the shaker into the glass, ensuring the ice cubes remain in the glass.

Top the glass with club soda or sparkling water, filling it to the brim.

Give the drink a gentle stir to incorporate the club soda.

Optional: Garnish the drink with fresh blueberries, sprigs of mint, and lime wedges.

Serve your blueberry lavender mojito immediately and enjoy!
