Preheat oven to 375°F and set a rack to the middle position. In a skillet over medium heat, fry bacon until crisp, about 12 minutes. Drain on paper towels; then crumble into in baked pie shell.

In a medium-size bowl, beat eggs lightly. Add cream, pumpkin purée, salt, spices, and cheese, and whisk just until blended. Pour mixture into crust, leaving about a quarter inch headroom. (Bake any leftover custard separately in a buttered ramekin.)

Bake until custard is set and puffed, 30–35 minutes. Serve warm.

In a medium-size bowl, whisk together flour, sugar, and salt until well combined.

Sprinkle butter over flour mixture, and use your fingers to work it in (rub your thumb against your fingertips, smearing the butter as you do). Stop when the mixture looks like cornmeal, with some pea-size bits of butter remaining.

Sprinkle 3 tablespoons ice water on top, and stir with a fork until dough begins to come together. If needed, add another tablespoon ice water.

Turn out onto a lightly floured surface and knead three times, or just enough to make a cohesive dough—don’t overmix!

Gather into a ball; then press into a disk and wrap in plastic. Refrigerate 30 minutes.
