Blackberry jalapeño syrup recipe:
½ cup white sugar
½ cup water
½ cup fresh blackberries
1 jalapeño, seeded, deveined and diced (if you don't love spice, use half of a jalapeño)
Instructions
For the simple syrup:
Combine the sugar and water in a small saucepan over medium heat. Whisk together until sugar is dissolved, about 2-4 minutes.
Remove from heat then pour into a mason jar or glass jar with the lid off. Let cool, approximately 20-30 minutes.
For the blackberry jalapeño syrup:
Once cool enough, transfer the simple syrup to a small food processor or blender, then add the fresh blackberries and diced jalapeño. Pulse or blend until smooth.
Place a fine mesh sieve/strainer over a glass bowl, then pour the simple syrup mixture into the sieve. Using a spatula, press down until all of the liquid is removed.
For the margaritas:
When ready to prepare the margaritas, rim 2 short glasses with lime juice then dip both into a dish filled with white sugar. Add 4-5 ice cubes per glass.
Next, fill a cocktail shaker with the tequila, Cointreau, lime juice, approximately ½ cup of the blackberry jalapeño syrup and 6-8 ice cubes.
Shake vigorously then strain the margaritas into the prepared glasses.
Garnish with lime slice and fresh blackberries, then serve.
