Preheat oven to 350°F.
Prepare the pumpkin as though you were going to make a jack-o-lantern, but stop short of carving the face. (Cut off the top; remove the seeds and stringy stuff.)
Place onion, bread, cheese, horseradish, and mustard inside the pumpkin. Mix with your hands until well combines.
Add milk and broth (as much as will fit - you can adjust the amounts) along with the seasonings. Stir it up.
Line the pumpkin lid with a piece of foil, and place it on top. Place the filled pumpkin in an ungreased baking pan.
Bake until the pumpkin is tender (about 2 hours). To test for tenderness, remove the lid, and gently stick a fork into the side. It should go in easily.
To Serve: Scoop deeply to bring up some pumpkin pieces from the sides and bottom along with the soup. If desired, top with some crunchy rye croutons.
Yield: 4 to 6 servings

"No kettle necessary! This wonderfully filling soup gets baked right inside the pumpkin, and the whole tureen can be brought to the table as an edible centerpiece.
For the broth You can use homemade stock, vegetable bouillon, or canned vegetable broth. Water will work, if you are brothless."
