01 - Preheat the oven to 375°F (190°C). Line a pie dish with the crust and press gently into the bottom and sides. Prick the base with a fork and bake for 10 minutes. Remove and let cool slightly.
02 - In a large bowl, whisk together pumpkin puree, heavy cream, brown sugar, granulated sugar, eggs, cinnamon, nutmeg, ginger, cloves, and vanilla extract until fully combined and smooth.
03 - Pour the pumpkin mixture into the partially baked crust. Level the top with a spatula and bake for 40-45 minutes, or until the filling is set and a knife inserted into the center comes out clean. Let cool completely at room temperature.
04 - While the pie cools, melt butter in a medium saucepan over medium heat. Add brown sugar and cook 2-3 minutes, stirring until dissolved and mixture bubbles.
05 - Add heavy cream to the saucepan, stirring continuously until caramel thickens slightly, about 2-3 minutes. Remove from heat and mix in vanilla extract and sea salt. Allow to cool for several minutes.
06 - After the pie has cooled, pour caramel sauce evenly over the top. Sprinkle chopped pecans over the caramel and gently press them in.
07 - Refrigerate the pie for at least 2 hours until the caramel is set. Serve chilled.
