Milk Gelato (Fior di Latte Gelato)

Bring cream and 2 cups of the milk to a simmer in a medium saucepan over medium heat. Meanwhile, dissolve sugar and cornstarch in the remaining milk in a small bowl.

Remove pan from heat and stir in milk-cornstarch mixture. Return pan to medium heat and cook, stirring constantly, until mixture comes to a boil and thickens slightly, about 10 minutes. Stir in preserves, strain into a bowl, and set aside to cool. Cover and refrigerate until well chilled, 2-3 hours.

Process mixture in an ice cream maker according to manufacturer's directions.
