- 300ml milk
- 1 vanilla pod
- 4 egg yolks
- 100g natural sweetener, such as Sweet Freedom
- 300ml natural yoghurt
For the raspberry ripple
- 150g raspberries
- 50g natural sweetener, such as Sweet Freedom
Pour the milk into a pan, split the vanilla pod lengthways and scrape the seeds into the milk. Add the pods and heat the milk until hot but not boiling. Remove from the heat and allow to infuse for 30 minutes.
Whisk together the natural sweetener and egg yolks. Bring the milk up to the boil and pour onto the egg yolks, whisking continuously. Return to the pan and simmer and stir continuously until the custard thickens slightly, without boiling. Sieve into a clean jug and stir in the yoghurt then cover the surface with baking parchment and leave to cool then chill until required, preferably overnight.
Blitz together the raspberries and natural sweetener then sieve to remove the seeds. Pour the chilled custard into an ice cream maker and churn until it is thick and creamy. Spoon a layer of the ice cream into a freeze proof container then drizzle with some raspberry purée. Repeat with the remaining ice cream and raspberry purée then freeze until required.
