Winter squash is a fall vegetable, so it is seasonal and relatively inexpensive. You have many different options, including kabocha, butternut, acorn, spaghetti, and hubbard squashes. And, hey, let's include pumpkin.
In
How to Cook Everything, Mark Bittman lists steaming, braising, braising and glazing, and roasting as the best methods for cooking.
The Flavor Bible by Karen Page and Andrew Dornenburg lists bake, braise, grill, mash, puree (hi, gobbo), roast, saute, and steam as techniques. Their most highly recommended flavor pairings with winter squash are apples, butter, garlic, nutmeg, onions, sage, brown sugar, and thyme.
So, cook something using any variety of winter squash and discuss it by Monday, November 26. You are encouraged to post pics, not just of the final dish, but also during stages of cooking. If you can't take pictures while cooking, perhaps a shot of your ingredients/mise en place before you start? I encourage people to cook, even if they are not into haute cuisine or food porn. This is a cheap ingredient, so it is easy to experiment with.
If anyone wants make something but has no clue of what to cook, I (and probably other posters) can give you ideas. Just tell me what sort of thing you want to cook, what other ingredients you want to use, and whatever limitations you have (please, state immediately if you are a vegetarian).
Also, use this thread to discuss how we want to handle this (including a better name?). In the past, there was a OOT Iron Chef series of threads that eventually died. They had posters prepare an appetizer, entree, and optional dessert using the secret ingredient. Then, there was voting, and the winner usually got to pick the next ingredient (sometimes put up to a vote). Do we want a formal competition with rules? If so, what rules? If not, how do we determine the next ingredient? I guess we'll see how many people participate and go from there.
Also, you can just talk about squash. What is your favorite squash dish? Mine is
ginataan kalabasa, a Filipino with squash cooked in coconut milk, with green beans and shrimp as optional ingredients.
