Are you a marathoner? Did you get voted "Most Likely to Persevere" in high school? If so, this is the recipe for you. It's going to take a while, and you're going to be elbow-deep in squash innards.
But wait for the adrenaline rush when you see how magnificently spectacular a slice of a 6-squash squashducken looks on the plates of your Thanksgiving guests.
A note on the squash: I chose my squash based on size and appearance. I went to the market with the goal of finding the largest and smallest edible squash I could find. I would recommend asking the vendors which squash taste the best, as I've had some experience with not-so-tasty "edible" squash. I've found that sweet dumpling, carnival, kuri, blue hubbard, acorn, honey nut, and buttercup work well. —Sarah Jampel
