Instructions: Ravioli: Preheat oven to 450 degrees. Place squash on a baking sheet and roast until soft. Scoop out flesh and run though a food mill.

Place the puree into a medium saucepan and cook over low heat until almost dry. Add the remaining ingredients and season with salt and pepper to taste.

Lay a sheet of pasta dough on a lightly floured work surface and distribute a heaping teaspoon-sized portion of the filling at least 2 inches apart. Use your fingertip or a brush to moisten the edges of the pasta sheet with the egg wash. Carefully place a second sheet of the pasta dough on top of the first and press with your fingertips to separate the rows of filling. Repeat with the remaining dough.

With a ravioli cutter or pastry wheel, cut along straight lines on the vertical and horizontal to form each ravioli square. Press the edges closed with your fingertips to seal well.

Bring a large pot of salted water to a boil. Carefully drop in the ravioli and cook for about 5 minutes. Drain, plate and spoon butter sauce over and garnish with finely chopped chives.

Brown Butter Sauce: Melt butter in a medium saute pan over medium-high heat. Add hazelnuts and cook until the hazelnuts are golden brown. Add the heavy cream and cook for 1 minute. Add the sage and season with salt and pepper, to taste.
