*Reduce the apple cider the same day you make the cheesecake, but make the caramel about an hour before you plan to serve the cheesecake.
Add the apple cider to a large pot and boil for about one hour until the cider is reduced down by more than ¾ of the way into a sticky syrup. Transfer to a heatproof bowl and refrigerate until ready to use.
4 cups pure apple cider
While the apple cider reduces, toast the pecans over medium heat until fragrant and slightly darker in color. Transfer to a plate to cool.
1 cup pecan halves or pieces
Measure out ½ cup of apple cider reduction (150g) and heat in a medium saucepan over medium heat until it becomes a syrup consistency and starts to bubble.
Add the white and brown sugars, butter and heavy cream and stir occasionally until the mixture begins to bubble and reaches 230℉.
1 cup granulated sugar, ½ cup light brown sugar, ½ cup unsalted butter, ⅓ cup heavy whipping cream
Remove from the heat, then stir in the flaky salt and cinnamon. Stir in the pecans, then transfer to a heat proof bowl. Continue stirring occasionally to release the heat and cool it down a bit.
2 teaspoons flaky sea salt, ½ teaspoon ground cinnamon
When ready to serve, remove the cheesecake from the spring form pan and get rid of the parchment paper. Slice the cheesecake, pour the caramel onto slices, and enjoy!
