I've struggled to find real passion fruit puree so decided to try with mango & passionfruit smoothie from Aldi (yes, really!) "...apple/passion fruit/lemon juices not from concentrate + mango, banana purées" and it makes for a truly delicious and rich PSM. I go with 50 ml (DIY infused) vanilla vodka, 25 ml PF liqueur (again DIY = fresh PF, simple syrup, vanilla bean, vodka to 10% ABV), 100 ml Aldi mango/PF smoothie, 20 ml lime juice and ½ PF flesh. Shaken/sieved/garnished in the normal way.
