Directions

• GnocchiScrub potatoes with vegetable brush under cold running water. Peel potatoes and cut into 3-inch chunks.
• Place potatoes in large saucepan or pot and add cold water to cover completely. Heat to boiling, then reduce heat to simmer. Cover and cook until tender, about 10 to 15 minutes.
• Drain potatoes well and turn into large bowl. Beat egg yolks and gradually stir into potatoes until blended. Stir in flour but don't over-mix; season with salt and pepper. Divide dough into three portions.
• On lightly floured work surface, using the palms of your hands, roll each portion of dough into a rope about inch in diameter; cut into 1-inch pieces.
• Place gnocchi on lightly floured baking sheet. Repeat with remaining dough. Place gnocchi in freezer until hardened.
• Arugula PestoMeanwhile, prepare pesto by combining all ingredients in food processor fitted with metal blade. Blend until pured; set aside.
• To prepare, fill large saucepan or pot 2/3 full of water. Bring to a boil. Add enough gnocchi to fill but not overcrowd.
• Simmer until gnocchi floats, about 5 to 7 minutes. Repeat with remaining gnocchi, if needed. Drain well and turn into large bowl.
• While gnocchi are cooking, heat pesto in saucepan or skillet. Pour over gnocchi in bowl and gently toss until all gnocchi are coated with pesto.
• Grate a small amount of Pecorino cheese over each serving.
