This dish, inspired by Osteria Francescana's iconic 'From Modena to Mirandola,' captures the culinary spirit of Emilia-Romagna with tender pork, creamy polenta, and a rich balsamic-fig glaze.
**Prepare Glaze:** Combine balsamic vinegar and chopped figs in a small saucepan. Bring to a simmer over medium heat, then reduce heat to low and cook, stirring occasionally, until thickened to a syrupy consistency (about 10-15 minutes). If too tart, add brown sugar. Set aside.
**Prepare Prosciutto Crisps:** Preheat oven to 375°F (190°C). Lay prosciutto slices on a baking sheet lined with parchment paper. Bake for 8-12 minutes, or until crispy. Remove and let cool. Break into pieces.
**Cook Polenta:** In a medium saucepan, bring chicken broth to a boil. Gradually whisk in the instant polenta, stirring constantly to prevent lumps. Reduce heat to low, cover, and cook for 5-7 minutes, stirring occasionally, until thick and creamy. Stir in Parmigiano Reggiano, butter, and salt to taste. Keep warm, covered.
**Cook Pork:** Pat pork tenderloin dry with paper towels. Season generously with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear the pork tenderloin on all sides until golden brown, about 2-3 minutes per side.
**Finish Pork:** Reduce heat to medium-low. If your tenderloin is thick, you can transfer the skillet to the preheated oven (if oven-safe) to finish cooking for 10-15 minutes, or continue cooking on the stovetop, turning occasionally, until an internal temperature of 145°F (63°C) is reached. Remove from heat, cover loosely with foil, and let rest for 5-10 minutes.
**Assemble Dish:** Slice the rested pork tenderloin into medallions. Divide the creamy polenta among four plates. Arrange pork medallions on top of or next to the polenta. Drizzle generously with the balsamic-fig glaze. Garnish with crispy prosciutto pieces, fresh sage leaves, and a sprinkle of extra Parmigiano Reggiano if desired. Finish with a small drizzle of extra virgin olive oil.
