Pineapple Upside Down Cake in frozen form! No cake in this version - just tropical pineapple sorbet topped with brown sugar caramel sauce and those classic maraschino cherries.
In a blender, purée pineapple and its juice until smooth. Refrigerate until thoroughly chilled. Freeze according to your ice cream maker instructions.
In a small saucepan over medium heat, combine brown sugar and butter until melted and bubbly. Whisk in cream and bring to a bubble again. Continue stirring about 5 minutes until sauce begins to thicken. Remove from heat and stir in vanilla and salt. Sauce will continue to thicken as it cools.
Serve caramel sauce over sorbet and top with a cherry.
