Preheat oven to 325°F (163°C). Place 6 ramekins in a large baking dish.
In a saucepan, combine cream and milk. Heat over medium until just steaming (not boiling), then remove from heat.
In a medium bowl, whisk egg yolks and sugar until pale and creamy. Add pumpkin, vanilla, cinnamon, nutmeg, and salt. Mix well.
Slowly pour the warm cream mixture into the pumpkin mixture, whisking constantly.
Strain the custard through a fine-mesh sieve into a large measuring cup (for easy pouring!).
Divide custard evenly among ramekins. Fill the baking dish with hot water halfway up the sides of the ramekins.
Bake for 35–45 minutes, or until centers are set but still slightly jiggly.
Carefully remove ramekins from water bath and cool to room temp. Chill at least 4 hours or overnight.
Just before serving, sprinkle 2 tsp sugar evenly over each custard. Torch until golden and crisp. Let sit 1–2 minutes so the top hardens.
