Take the cocktail shaker and add the fresh blackberries and jalapeno (optional) to the cup.
Using the muddler, begin smashing the blackberries and jalapeno together until the ingredients break down, forming a syrup. This step takes a couple of minutes. You will know the syrup is ready when it has transformed into a soup like texture.
Now, add in a few ice cubes and begin adding the remaining ingredients. Pour in the tequila, sour mix, honey and orange bitters.
Shake vigorously for at least 30 seconds. It will be helpful to use a straw to taste the recipe and adjust to your liking.
Begin by adding a few ice cubes to each glass. Using the small strainer, pour the contents out of the shaker into each glass being careful to divide evenly.
Then, garnish the drink with fresh blackberries, jalapeño and mint! Now it's time to enjoy!
