Ravioli d'Ossobuco Dorato con Salsa Gremolata al Limone e Zafferano

Prepare the Ossobuco Filling: Pat the veal shanks dry and dredge lightly in 50g all-purpose flour, shaking off excess. Heat olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Sear the veal shanks on all sides until golden brown, then remove and set aside.

Add the finely diced onion, carrot, and celery to the pot. Sauté for 8-10 minutes until softened and lightly caramelized. Add the 2 cloves of minced garlic and cook for another minute until fragrant.

Deglaze the pot with white wine, scraping up any browned bits from the bottom. Let it simmer until reduced by half.

Return the veal shanks to the pot. Add chicken or beef broth, diced tomatoes, bay leaf, and thyme sprigs. Season with salt and black pepper. Bring to a simmer, then reduce heat to low, cover, and braise for 2.5 to 3 hours, or until the veal is fork-tender and falling off the bone.

Remove the veal shanks from the pot. Discard the bay leaf and thyme sprigs. Shred the meat from the bones, discarding any fat or gristle. Finely chop the shredded meat.

Strain the braising liquid and vegetables through a fine-mesh sieve, pressing on the solids to extract all liquid. Discard the solids. Reduce the strained liquid over medium-high heat until it thickens into a rich sauce (about 150-200ml).

Combine the finely chopped veal meat with a few tablespoons of the reduced braising sauce until it forms a moist, flavorful filling. Adjust seasoning if necessary. Let cool completely before making the ravioli.

Prepare the Pasta Dough: On a clean work surface, make a well with the 300g "00" flour. Crack the 3 large eggs into the well. Using a fork, gently whisk the eggs, gradually incorporating flour from the sides until a shaggy dough forms. Knead the dough for 10-15 minutes until it is smooth, elastic, and no longer sticky. Wrap in plastic wrap and let rest at room temperature for at least 30 minutes.

Assemble the Ravioli: Divide the pasta dough into four portions. Working with one portion at a time (keep others covered), flatten it slightly and pass it through a pasta machine, starting from the widest setting and gradually decreasing until you reach a thinness of setting 6 or 7 (on a 9-setting machine), or until it's thin enough to see your hand through.

Lay one pasta sheet on a lightly floured surface. Place small spoonfuls (about 1 teaspoon) of the cooled ossobuco filling onto the pasta sheet, spacing them about 1.5 inches apart. Lightly brush the pasta around the filling with water. Carefully lay a second pasta sheet over the first, pressing down gently around the filling to remove air and seal the ravioli. Using a ravioli cutter or a knife, cut out individual ravioli. Ensure the edges are well-sealed. Place the finished ravioli on a semolina-dusted baking sheet. Repeat with the remaining dough and filling.

Prepare the Gremolata: In a small bowl, combine finely chopped parsley, lemon zest, and the remaining 1 clove of minced garlic. Set aside.

Cook the Ravioli: Bring a large pot of salted water to a rolling boil. Carefully add the ravioli and cook for 3-4 minutes, or until they float to the surface and the pasta is al dente. Reserve about 1/4 cup of pasta cooking water before draining.

Prepare the Saffron Butter Sauce: While the ravioli cook, melt the unsalted butter in a large skillet over medium heat. Add the steeped saffron threads (with their liquid). Cook gently until the butter is fragrant and lightly golden.

Transfer the drained ravioli directly into the skillet with the saffron butter. Add the grated Parmigiano Reggiano and a splash of the reserved pasta cooking water. Gently toss or swirl the pan to emulsify the sauce, coating each raviolo beautifully.

Serve immediately, garnished generously with the fresh gremolata.
