2 pounds peaches peeled, pitted and coarsely chopped
1/2 cup plus 2 tablespoons sugar
1/2 teaspoon fresh lemon juice
1 pinch salt
1-1/3 cups heavy cream
1/2 cup milk
1/2 teaspoon ground cinnamon
In a medium saucepan, combine the peaches, 7 tablespoons sugar, the lemon juice and salt. Cook over medium heat, mashing, until jam like, about 15 minutes. Let cool.
In a medium bowl, whisk together the cream, milk, remaining 3 tablespoons sugar and the cinnamon until the sugar is dissolved. Stir in the peach mixture and refrigerate for 4 hours.
Using an ice cream machine, process the peach mixture according to the manufacturer’s instructions. Transfer to an airtight container and freeze until firm, about 4 hours.
