I thought I would share the following two non-recipes I wrote down for my Aunt Nan after I made it when she was visiting last Thanksgiving. I actually served it in the toasted hollowed out pumpkin. In America I had more tools and seasoning. Here in Israel, I just bought a food processor and I don't use boxed broth.
I scraped out all the meat from the pumpkin (or roast the squash until you can peel off the skin easily) (toss the seeds). For Pumpkin - I would start this roasting in the oven if you have that available, but you'll need a really big pan (otherwise just add raw and cook longer). Then I fried up 3 chopped carrots, 3 stalks of celery, I think 1-2 onions, a couple cloves of garlic, mushrooms and anything else you want (less for smaller squash). When it's soft, add more oil and flour (I guess this is optional, but I like the flavor it adds to creamy, non-dairy soups.) I use grapeseed oil, canola is fine. Let the flour cook and keep scraping the bottom. Add a little broth now if it's sticking too much. Add the pumpkin (if it's still raw, it just takes longer) Here I added a whole carton of "Imagine No-chicken broth", but you could use other liquids, and scrape up all the flour. Add any fresh herbs like thyme, sage, or rosemary. My soup comes out a little greenish, but it's yummy, use less herbs if this would bother you. While it's cooking/simmering add other seasonings. I like to pull my spices out and sniff them to decide on a good combination, but for this soup, I used a mix of savory (listed above) and sweeter: nutmeg, cinnamon, allspice... Sea salt, a little fresh ground pepper or chili pepper, I added a drop of honey and agave syrup...You could probably get away with less or different ingredients, I'm just trying to remember what I did. When everything if soft and smells good, blend with a hand blender or in food processor.
A delicious variation I just tried was more Indian style I used more fresh garlic, lots of Cumin, chili powder, a little ginger, and cinnamon, and a can of tomatoes (added in the beginning and completely blended). Good luck!
