First, you need a fresh pumpkin.
Go to your local pumpkin patch - there are a lot of them selling this time of year.
Pumpkins this size will give you enough for soup and still have some left over for pie.
You will also need a 5-pound roasting chicken.
Quarter the chicken and place in it a large pot of water to stock.
Wash the pumpkin, cut it into quarters and remove the seeds.
Roast on the center rack of a 365-degree oven for about 90 minutes.
Then set aside to cool.
Add some onion and leek to your chicken stock.
When the pumpkin is cool enough to handle, strain your stock.
Return it to the pot and add some curry and white pepper.
Skin half of the pumpkin, cut into large chunks, and add to the seasoned chicken stock.
Add just a little heavy cream - a couple of tablespoons is about enough.
Use an immersion blender to smooth it out.
Taste it and add more of whatever you think is missing.
If you add more pumpkin, use the blender again.
Add a couple of dried chilis - you can find these at Latino, Asian or Indian grocery stores- and let the whole thing simmer for about 45 minutes.
Serve with a dollop of creme fraiche.
