Ingredients:
- 2 lbs (900g) ripe plums, pitted and quartered
- 1/2 cup (100g) granulated sugar
- 1 tsp (2.6g) ground cinnamon
- 1 tbsp (15ml) lemon juice
- 1 small pinch (1g) salt
- 2 cups (480ml) heavy cream, chilled
- 1 cup (240ml) whole milk, chilled
- 3/4 cup (150g) granulated sugar
- 1 tsp (5ml) vanilla extract
- 1/4 tsp (1.5g) salt
Instructions:
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Toss the quartered plums with sugar, cinnamon, lemon juice, and salt until evenly coated.
- Spread the plums in a single layer on the baking sheet and roast for 25–30 minutes until the plums are softened and the juices have turned into a thick, mahogany-colored syrup.
- Allow the plums to cool slightly, transfer the fruit and syrup to a blender, pulse until smooth, and chill the puree in the refrigerator for at least 2 hours.
- In a saucepan over medium heat, whisk together the whole milk, sugar, and salt until the sugar is completely dissolved, ensuring the mixture does not boil.
- Remove the saucepan from heat and stir in the vanilla extract.
- Stir in the chilled heavy cream, pour the mixture into a bowl, cover, and refrigerate for at least 4 hours or overnight.
- Slowly whisk the chilled roasted plum puree into the chilled cream base until the color is a consistent, pale purple.
- Pour the mixture into your ice cream maker and churn according to the manufacturer's instructions.
