The semester is over, so I had time to actually come up with a new recipe tonight, for a curried chestnut soup. 
So seasonal!
You can roast the chestnuts yourself — a little more effort, but it’s tasty to peel and eat some of that sweet nuttiness while it’s hot. Just be careful when cutting crosses into the chestnuts before you roast, so your knife doesn’t slip. Or you can buy a jar of them already roasted, though you may need to find a specialty shop for that. If you cleverly reserved turkey stock after Thanksgiving, you could pull some out of the freezer and use it for this. That was my plan, but I forgot to freeze the extra stock until it was too late this year. Oh well.
I used Sri Lankan roasted curry powder, but I think any standard South Asian curry powder would be tasty. The complex spicing balances the sweetness of the chestnuts and the saltiness of the prosciutto (or the mushrooms sautéed in butter with salt). Substitute in vegetable oil, vegetable stock, and coconut milk to make this a filling, nutritious, and delicious vegan meal.

Curried Chestnut, Leek, and Carrot Soup, with Fried Prosciutto (or Sautéed Mushrooms)
(serves 4, about 30 minutes (aside from chestnut roasting time))
3 T unsalted butter
2 leeks, white parts sliced thin
2 carrots, peeled and chopped finely
1/2 t. salt
1 t. pepper
about 15 oz. (3 c.) roasted and peeled chestnuts
6 c. chicken stock
1 t. curry powder
1/4 c. heavy cream
additional salt and pepper to taste
1/2 t. lime juice
Optional: either fried prosciutto or mushrooms sautéed in butter for garnish — make them while the soup is simmering
1. Heat butter in large soup pot and stir in leeks, carrots, salt, and pepper. Sauté, stirring, about 5 minutes.
2. Add chestnuts and chicken stock, bring to a boil, then turn down to a simmer. Simmer for 20-30 minutes.
3. Transfer soup carefully to blender — I’d use a large ladle rather than trying to pour a pot of hot soup! (If you have an immersion stick blender, that’s even easier.) Purée, and return to pot. (It’s fine to leave a cup or so of broth in the pot; just stir it into the purée when you return it to the pot.) Add cream and stir. Taste and add salt / pepper as desired; if the soup is too thick, add a little more stock. Stir in the lime juice and simmer a few more minutes, until well blended.
4. Serve hot, garnished with prosciutto or mushrooms. (I don’t recommend both together — I tried it, and oddly, they clash.) If you want to make it even prettier, you could drizzle a little cream into the bowl, or add a scattering of chives. Mmm….
