Cauliflower Ravioli with Guanciale

Step 1

pasta: Mix semolina flour and salt in large bowl. Whisk eggs and yolks in small bowl. Gradually stir egg mixture into flour. Turn dough out onto lightly floured surface. Knead until smooth and elastic (dough will be sticky). Wrap in plastic wrap; chill 1 day.

Step 2

filling: Melt butter with oil in large skillet over medium heat. Add cauliflower; sprinkle with salt and pepper and sauté until golden, about 7 minutes. Add 1/2 cup water. Cover and simmer until cauliflower is tender, about 5 minutes. Uncover and cook until dry, about 3 minutes. Cool completely.

Step 3

Blend ricotta, 6 tablespoons Parmesan, and mascarpone in processor until smooth. Add cauliflower and blend until filling is smooth. Season with salt and pepper. DO AHEAD Can be made 1 day ahead. Transfer to bowl, cover, and chill.

Step 4

sauce: Sauté guanciale in large deep skillet over medium-high heat until golden and crisp. Add broth and butter. Boil until sauce thickens and is reduced to 1 1/2 cups, about 12 minutes. Chill up to 4 hours.

Step 5

Line large rimmed baking sheet with parchment paper; dust with all purpose flour. Divide dough into 3 pieces; cover with plastic wrap to prevent drying. Set pasta machine to widest setting. Flatten 1 dough piece into rectangle; run though machine. Fold in half, end to end, and run through machine again. Continue, adjusting to next-narrower setting after every 4 or 5 passes and dusting with flour as needed to keep from sticking, until sheet is about 24 inches long and about 1/16 inch thick. Cut sheet in half crosswise.

Step 6

Drop filling onto 1 dough strip by heaping teaspoonfuls, spacing 1 1/2 inches apart. Brush dough with water around each mound. Top with second dough strip; press around each mound to seal. Cut each ravioli into 2-inch square. Arrange on prepared sheet; cover with kitchen towel. Repeat with remaining dough and filling. DO AHEAD Can be made 3 hours ahead; chill.

Step 7

Cook ravioli in large pot of boiling salted water until just tender, stirring occasionally. Drain well. Rewarm sauce. Add ravioli and toss over medium-high heat until sauce coats ravioli, about 2 minutes. Transfer to shallow bowl. Serve, passing grated Parmesan.
