Muddle the dragonfruit in the shaker, then add remaining ingredients, shake vigorously using ice cubes, then pour into a frozen coupe glass.
The "problem" with dragonfruit is that the juice cannot be muddled out, it remains a juicy/pulpy consistency. So I don't "strain" the shaken cocktail into the glass, rather, I "encourage" the muddled dragonfruit into the glass to keep it's flavor. Thus can the actual fruit be tasted, and the seeds, which are edible, act as something of a garnish.
All SWOboys enjoy a well-executed UNREP.
