The texture of this is like frozen custard. I think I would add even more peaches though.
2 1/2 cups sugar
1 cup whole milk (I used half-and-half)
4 large egg yolks
2 cups fresh peaches (about 4 of them), peeled, pitted, and pureed
1 cup half-and-half
1 cup whipping cream
1 t. vanilla extract
1. In medium saucepan, whisk together sugar, milk, egg yolks, and a pinch of salt. Place pan on medium-high heat, and whisk until mixture comes to a simmer. Lower heat to medium and whisk mixture 5 minutes, or until it begins to thicken. Strain into large bowl, then whisk in peaches, half-and-half, cream, and vanilla. Cover with plastic wrap and refrigerate 2 hours, or until chilled.
2. Pour mixture into ice cream maker; process according to manufacturer's instructions.
