In a large bowl, whisk together the cream, vanilla, yolks, sugar, pumpkin, cinnamon, nutmeg, and ginger. Blend well. Strain into a large bowl, skimming off any foam or bubbles.
Divide mixture among 6 - 8 ramekins or custard cups. Place in a water bath and bake until set around the edges, but still loose in the center, about 30 or 40 minutes. Remove from oven and leave in the water bath until cooled.
Remove cups from water bath and chill for at least 2 hours, or up to 2 days.
When ready to serve, sprinkle about 2 teaspoons of sugar over each custard. Take your torch and caramelize the top for a few seconds. If you don't have a torch you can put under the broiler for 1 to 2 minutes. Use an inverted pan if needed to get it to 5 inches from flame.
Notes
This is the perfect dessert for fall gatherings. It can chill in the fridge for up to 2 days in advance, making it easy to make ahead so you can enjoy the event.
