Cut the pumpkin into large cubes, sprinkle with a little sugar, and bake at 200 degrees until done.
Beat the eggs well with the sugar and vanilla, gradually adding the milk and cream while mixing.
In a dry pan, heat the sugar for caramel without stirring until it begins to brown at the bottom.
Gently stir until fully melted and caramelized to a medium dark caramel.
Immediately pour the caramel into the bottom of a deep baking dish.
Spread the pumpkin over the caramel, pour the mixture on top, and bake for 60 minutes at 150 degrees in a larger dish filled with water for a water bath.
