Pistachio kulfi ice lollies

Method

1. Put the milk in a heavy-based saucepan or frying pan on the widest hob, then slowly bring to a simmer. Very gently bubble to reduce by just over half – it will take around 2 hours and you’ll need to stir it every 5 minutes or so to make sure it doesn’t catch.
2. Once it has reached this volume, stir in the caster sugar, salt and cardamom, then cook for another 5-10 minutes, stirring, until the sugar has dissolved. Transfer to a mixing bowl and allow to cool completely, then strain through a sieve, pushing the mixture through – discard what’s left in the sieve.
3. Grease the lolly moulds lightly with the oil. Stir the pistachios into the kulfi (they’ll slowly float to the top), then pour the mix into the moulds. Put them in the freezer. If you’re using wooden lolly sticks, freeze the lollies for 1 hour, then push the sticks into the centre of each mould. Freeze for at least 8 hours, or up to 1 month.
4. To serve, remove the moulds from the freezer and pull the lollies out – if they stick, dip the moulds briefly into hot water or leave at room temperature for 10-15 minutes.
