Pulse the mango in a food processor until you achieve pea-size chunks. Add the condensed milk, vanilla and salt. Pulse to combine, then remove to a medium bowl and fold in the jalapeno and lime zest; set aside.
Whip the cream with a mixer on medium-high speed until firm peaks form, about 2 minutes. Fold about 1 cup of the whipped cream into the mango mixture with a rubber spatula until combined, then fold the lightened mixture into the whipped cream until well blended. Pour into a chilled 9-by-5-by-3-inch metal loaf pan, and freeze, covered, until until solid and scoopable, about 5 hours. Serve topped with a pinch of lime zest and chili powder.
