Prepare the pie crust as your recipe directs.
Set your oven to 425°F (220°C).
In a large bowl, beat the eggs until smooth. Add in the maple syrup, salt, and spices (cinnamon, ginger, nutmeg, and cloves), and mix well. Next, add the pumpkin purée, heavy whipping cream, and vanilla extract, stirring until everything is fully combined.
Pour the filling into a 9-inch pie pan lined with your prepared crust.
Place the pie on a lower rack, but not at the very bottom—closer to the bottom to ensure the crust bakes evenly without burning. Bake for 15 minutes at 425°F. Then, lower the oven temperature to 400°F and continue baking for 45-50 minutes, or until the filling is set about 3 inches from the edge. The center should still have a slight wobble.
If the edges of the pie start to brown too quickly during baking, cover them with foil. To do this, cut a large circle in tin foil, then carefully place it over the pie to cover the edges, but the center remains exposed. This will help protect the crust while allowing the filling to continue baking evenly.
Remove the pie from the oven and let it cool on a wire rack. The filling will firm up as it cools. Once cooled, refrigerate the pie.
