Using a stand mixer or hand mixer and large bowl, whip the heavy cream until stiff peaks form.
In a separate bowl, stir together sweetened condensed milk, vanilla and salt until combined.
Fold the condensed milk mixture into the whipped cream very gently until completely combined.
Gently fold in the chopped peaches until evenly combined.
Pour half the mixture into a loaf pan and dollop with half of the peach puree, swirling with a knife. Pour the remaining ice cream mixture into the pan and dollop with the remaining puree, again swirling it with a knife.
Cover and freeze for at least 4 hours before serving.
