Ingredients:
- 2 lbs plums, pitted and halved
- 3/4 cup granulated sugar
- 1 tbsp lemon juice
- 1 whole vanilla bean, split and scraped
- 2 tbsp water
- 1 tbsp light corn syrup
- 1/4 tsp salt
Instructions:
- Preheat your oven to 375°F (190°C). Toss the halved plums with sugar and lemon juice in a 9x13 inch baking dish. Tuck the scraped vanilla bean pod and the seeds among the fruit.
- Roast for 30–40 minutes until the plums are tender and the edges are mahogany-colored and bubbling.
- Let the plums cool to room temperature in their own juices.
- Transfer the fruit, the syrupy liquid, and the vanilla seeds into a blender. Blend on high until the mixture is completely smooth.
- For an ultra-refined texture, pour the puree through a fine-mesh sieve into a bowl.
- To freeze using an ice cream maker: Pour the chilled puree into your machine and churn according to manufacturer instructions until it reaches a soft-serve consistency.
- To freeze without an ice cream maker: Pour the puree into a shallow metal pan. Freeze for 4–6 hours, stirring vigorously with a fork every 45 minutes to break up ice crystals.
