Step-by-Step Instructions
Step 1: Make the Pasta Dough
Mix the Ingredients: In a large mixing bowl, combine the flour and salt. Create a well in the center and crack in the eggs.
Incorporate the Flour: Using a fork, whisk the eggs gently, gradually incorporating the flour from the edges of the well until a dough starts to form.
Knead the Dough: Transfer the dough to a floured surface and knead it for about 10 minutes until smooth and elastic. If the dough is sticky, sprinkle with a little extra flour.
Rest the Dough: Wrap the dough in plastic wrap and let it rest at room temperature for at least 30 minutes.
Step 2: Prepare the Potato Filling
Boil the Potatoes: Place the potatoes in a large pot of salted water and boil until tender (about 20 minutes). Drain and let cool slightly.
Mash the Potatoes: Peel the potatoes and mash them in a bowl until smooth.
Combine Ingredients: Add the ricotta, Parmigiano-Reggiano, salt, pepper, and nutmeg to the mashed potatoes. Mix well until creamy. Taste and adjust the seasoning if needed.
Step 3: Roll Out the Pasta
Divide the Dough: Cut the rested dough into quarters. Keep the unused portions covered to prevent drying.
Roll the Dough: On a floured surface or using a pasta machine, roll out each portion into thin sheets (about 1/16 inch thick).
Cut the Tortelli: Using a knife or pastry cutter, cut the rolled dough into squares (about 2 inches wide).
Step 4: Assemble the Tortelli
Fill the Tortelli: Place a teaspoon of potato filling in the center of each square. Fold the dough over to create a triangle and press to seal, ensuring there are no air pockets.
Trim and Seal: Use a fork to press the edges for a decorative finish and extra sealing.
Step 5: Cook the Tortelli
Boil Water: Bring a large pot of salted water to a boil.
Cook the Tortelli: Drop the tortelli in batches into the boiling water and cook for about 4-5 minutes or until they float to the surface.
Drain: Use a slotted spoon to carefully remove the tortelli and transfer them to a serving dish.
Step 6: Serve
Prepare the Sauce: In a skillet, melt butter over medium heat. Add fresh sage leaves and cook until fragrant.
Coat the Tortelli: Add the drained tortelli to the skillet and gently toss to coat in the butter and sage.
Garnish and Serve: Serve warm, topped with extra Parmigiano-Reggiano cheese.
Variations
