2 1⁄2 oz Lime juice
1 t Lemon juice
1 1⁄2 oz Passion fruit syrup (see note)
1⁄4 oz Simple syrup
1 oz Demerara Rum
Shake everything except the 151, strain into a double old fashioned over crushed ice, float 151.
The best way to make passionfruit syrup is to take frozen passionfruit pulp, thaw it, and mix that with an equal amount of 1:1 simple syrup.
