Sweet Potato Bourbon Noodle Kugel

Preheat oven to 400u0b0F.
Wrap sweet potatoes individually in foil and roast in the oven until soft and completely cooked through, about 1 hour and 10 minutes. Let cool completely. Peel skin off sweet potatoes using your hands (and a table knife, if it helps), then puree with the bourbon in a blender or food processor until completely smooth. This should yield about 3 cups of puree. If you yield more than 3 cups, set the excess aside for another use or discard. (If you want, you can do this ahead and refrigerate the puree for up to 2 days.)
Lower oven to 350u0b0F.
In a pot of heavily salted water, cook the egg noodles al dente (about 5 minutes, or 2 minutes less than the package directions say). Pour into a colander to drain, running cold water over the noodles until they are cool to stop the cooking. Drain thoroughly.
In a very large bowl, beat eggs, then add brown sugar and beat just until combined. Add cottage cheese, melted butter, and the sweet potato puree, then mix with a rubber spatula until combined. Finally, add salt and the cooked noodles, and mix with a spatula until combined.
Pour noodle mixture into a 9x13-inch baking dish. Bake uncovered for 50 minutes (if noodles start to brown during this time, cover your baking dish with foil).
