Passionfruit, pineapple and vanilla icy poles

1.Stir sugar, vanilla seeds and 60ml water in a small saucepan over low heat to dissolve sugar, bring to the simmer, remove from heat and set aside to cool.

2.Strain two-thirds of the passionfruit pulp through a fine sieve, pressing solids with a spoon to extract liquid (discard solids). Whisk passionfruit juice, remaining passionfruit pulp, pineapple juice, lime juice and vanilla sugar syrup in a large bowl to combine and pour into desired moulds (around 80ml each). Freeze until half-frozen (1½ hours), insert icy-pole sticks and freeze until frozen (8 hours or overnight).

3.To serve, place moulds in a container of cold water that comes three-quarters of the way up the sides. Pull on sticks to release icy poles and eat immediately or store in the freezer for up to a month in an airtight container.
