Hot Pepper Fettuccine With Roasted Butternut Squash

Preparation

1. Step 1

   Make the dough: In a mixing bowl, combine flour, salt, paprika, cayenne and pimentón. In a separate bowl, beat eggs with 3 tablespoons water and 1 tablespoon olive oil. Pour egg mixture into the flour mixture and stir with chopsticks or a wooden spoon to combine until a rough dough is formed.

2. Step 2

   Turn dough out onto a work surface dusted with all-purpose flour and knead into a ball. Wrap dough in plastic and let rest at room temperature for at least 15 minutes. (It may appear dry or tough at first, but it will become hydrated and more relaxed after resting.)

3. Step 3

   Meanwhile, heat oven to 400 degrees. Put squash in a bowl, add 2 tablespoons oil, a generous amount of salt and pepper, a pinch of crushed red pepper, and the pancetta or bacon. Strip leaves from 1 sprig rosemary and 1 sprig sage, add to bowl, then toss well to coat.

4. Step 4

   Spread squash mixture on a baking sheet in an even layer and roast for 20 minutes, or until cooked and lightly browned. Adjust seasoning to taste and set aside.

5. Step 5

   Make the fettuccine: Roll out dough by hand or with a pasta machine into thin sheets (but not paper thin). Cut sheets into pieces approximately 6 by 9 inches. Dust each piece lightly with rice flour, stack them, and gently roll the stack into a loose cylinder, as if making a jelly roll. With a sharp knife, cut crosswise to make thin ribbons, about ⅛-inch wide. Dust a baking sheet with rice flour and arrange cut ribbons in a single layer to keep them from sticking together. Dust with more rice flour. Leave uncovered at room temperature.

6. Step 6

   Put 2 tablespoons olive oil in a large skillet over medium-high heat. Add onions, season generously with salt and pepper, and cook, stirring, until softened, 3 to 4 minutes. Add garlic, chopped rosemary and sage, and a pinch of crushed red pepper and cook for 1 minute. Add reserved squash, then fold in ½ cup ricotta and the lemon zest. Cook for 1 minute more and turn off heat.

7. Step 7

   Bring a large pot of generously salted water to a boil over high heat. Boil the pasta for 1 to 2 minutes, until al dente. Drain, reserving 1 cup of pasta cooking water.

8. Step 8

   Add pasta to the skillet, and gently fold ingredients together. Add 3 to 4 tablespoons pasta cooking water. Transfer to a warm serving platter, dot with remaining ½ cup ricotta and sprinkle with pecorino and parsley.
