Make sure your ice cream maker bowl is completely frozen—check your machine’s manual for timing.
In a high-speed blender, combine diced mango, lemon juice, and half the sugar. Blend until smooth—you should end up with about 2 cups of purée. Set aside.
1 ½ cups ripe mango, ¼ cup sugar, 1 tablespoon lemon juice
In a large bowl, whisk together the heavy cream, vanilla extract, salt, and remaining sugar until smooth. Stir the mango purée into the cream mixture until fully combined and velvety.
1 cup heavy cream, 1 teaspoon vanilla extract, ¼ teaspoon kosher salt
Pour the mixture into your ice cream maker and churn for about 25 minutes, or until it reaches a soft-serve texture.
Transfer the churned ice cream into a loaf pan or shallow container. Press plastic wrap or wax paper directly on the surface to prevent ice crystals. Freeze for at least 4 hours or until fully set.
Let it sit at room temp for 5 minutes before scooping. Serve in cones, bowls, or with fresh fruit!
