Fit the crust into the pie plate, crimp the edge, and refrigerate 15 minutes. Heat the oven to 400°F.
Line the crust with parchment, fill with pie weights, and bake 15 minutes. Remove the parchment and weights and bake 5 to 7 minutes more, until the bottom looks dry. Lower the oven to 350°F.
In a large bowl, whisk the pumpkin, brown sugar, cinnamon, ginger, nutmeg, cloves, and salt until smooth.
Whisk in the eggs and yolk, then the cream and vanilla, until just combined and smooth.
Pour the filling into the warm crust. Bake at 350°F for 45 to 55 minutes, adding a crust shield once the edges are golden, until the edges are set and the center jiggles slightly (about 175°F near the center).
Cool on a wire rack for about 2 hours, then refrigerate at least 2 hours, or overnight, before slicing. Serve with whipped cream.
