Macerate and prep the peaches
- Toss the diced fresh peaches with 1/4 cup granulated sugar and lemon juice, then let sit 30 minutes to macerate. Cover if possible so the juices pool and the fruit softens.
- Blend 2 cups of the macerated peach mixture until smooth, then set it aside and leave the remaining peaches chunky. The visual cue should be a smooth pale peach puree with leftover pieces visible.
Cook the peach custard base
- Heat the heavy cream and whole milk in a Dutch oven until steaming but not boiling. Keep heat at medium so the edges start to steam and small bubbles form around the rim.
- Whisk the 4 egg yolks with the remaining 1/2 cup granulated sugar until thickened and smooth. Stop when the mixture turns lighter in color and ribbons off the whisk.
- Whisk the steaming dairy slowly into the egg yolks to temper them. Pour in a thin steady stream while whisking to prevent scrambling.
- Return the mixture to the Dutch oven and cook to 175°F, stirring constantly, for about 10 minutes. The custard should coat the back of a spoon and hold a clear line when you run a finger through it.
- Strain the custard and whisk in vanilla extract, cinnamon, and the blended peach puree. Stir just until combined so the color becomes pale golden and creamy.
Chill, churn, and freeze
- Cool the custard completely using an ice bath, stirring occasionally, for about 4 hours total chilling time. The surface should feel cool to the touch and the custard should thicken slightly as it chills.
- Refrigerate the custard at least 2 hours after cooling, until very cold. The visual cue is a chilled, thick pourable custard with no warmth when you touch the container.
- Churn in an ice cream maker until thick and the texture looks like soft-serve. In the last 5 minutes, add the reserved chunky peaches so you see visible pieces throughout.
- Freeze at least 2 hours until scoopable. The ice cream should become firm enough to scoop cleanly without melting fast.
Notes
For best texture, cook the custard only until it reaches 175°F and stir constantly so it stays smooth when strained. Store covered in the freezer up to 2–3 weeks. Freezing is yes—scooping may soften slightly on the counter. For a lactose-light option, use lactose-free whole milk and lactose-free cream while keeping the same cooking temperature.
