Peach Frozen Yogurt

Purée the peaches in a blender until smooth. Blend in the sugar, lemon juice, and vanilla until the sugar has dissolved. Pulse in the yogurt until the mixture is smooth. Fold in the whipped cream and process in an ice cream maker, following the manufacturer’s instructions. Scrape the frozen yogurt into a nonreactive container and freeze further until firm, at least 3 hours.
