Preheat oven to 350 degrees F. In a small saucepan, heat cream over medium-high heat just until bubbly. Remove saucepan from heat and set side. In a large mixing bowl, combine egg yolks, eggs, ½ cup of sugar, canned pumpkin, cinnamon, ginger, salt and cloves. Whisk until just combined. Slowly whisk the hot cream into the egg mixture then set aside. Using a paring knife, cut off the tops of the baby pumpkins, reserving tops. Use a spoon to scoop out the seeds and discard. Place pumpkins in a roasting pan and divide custard mixture evenly among pumpkins. Place roasting pan in oven and pour hot water into the pan to reach halfway up the sides of the pumpkins. Bake 30–40 minutes or until center appears nearly set when gently shaken. Carefully remove the pan from the oven. Remove pumpkins from water and place pumpkins on a cooling rack. Cover and chill in refrigerator at least 1 hour or up to 8 hours. To serve, let custards stand at room temperature 20 minutes. Sprinkle custards with remaining sugar and torch to caramelize the sugar. Garnish with the reserved tops of the baby pumpkins. You may also wish to paint or draw a spooky face on the outside surface of the pumpkins to make tiny jack-o'-lanterns.
