Da Passion

Combine passion fruit juice and cream of coconut in a blender. Process until smooth, about 1 minute. Store in an airtight container in refrigerator up to 1 week. Shake well before using.

To make 1 drink, combine 6 tablespoons passion fruit–coconut mixture and rum in a cocktail shaker. Fill with ice; cover and shake until well chilled, about 12 seconds. Strain into a highball glass filled with ice, and top with Angostura bitters. Serve immediately.
