Arista alla Fiorentina

Ingredients

Equipment Needed

• •Heavy roasting pan or large cast-iron skillet
• •Instant-read meat thermometer
• •Sharp thin knife for making incisions

Instructions

1. 1

   Prepare the seasoning paste

   Strip the rosemary leaves from their woody stems. On a cutting board, combine the garlic cloves, rosemary leaves, sea salt, and black pepper. Chop them together, working the blade back and forth until you have a coarse paste. The salt acts as an abrasive, helping to break down the garlic and release the rosemary oils. You should smell the rosemary strongly. Add two tablespoons of the olive oil and work it into the paste.

   Do not use a food processor. The hand-chopped paste has texture and distributes better into the meat. A mortar and pestle is acceptable if you prefer.
2. 2

   Score and season the meat

   Remove the pork from refrigeration one hour before cooking. Using a thin, sharp knife, make deep incisions all over the meat, about two inches apart and one inch deep. Push small amounts of the rosemary-garlic paste into each incision with your finger, forcing it deep into the flesh. Rub the remaining paste over the entire surface of the roast. The meat should be fragrant and thoroughly coated.

3. 3

   Sear the roast

   Heat the remaining tablespoon of olive oil in a roasting pan or large oven-safe skillet over medium-high heat. When the oil shimmers, place the pork fat-side down and sear until golden brown, about 4 minutes. Turn and brown all sides. This creates the foundation for the crust. Transfer the pan to a rack and let the meat rest while the oven heats.

4. 4

   Roast slowly

   Heat the oven to 325°F. Place the pork fat-side up in the roasting pan. Pour the white wine around (not over) the meat. Roast uncovered for approximately 1 hour and 45 minutes to 2 hours, until an instant-read thermometer inserted into the thickest part (not touching bone) reads 145°F. Baste with the pan juices every 30 minutes.

   The USDA now considers 145°F safe for pork. The meat will be faintly pink at the center, juicy and tender. If you cook to 160°F as older recipes suggest, you will have dry meat. Trust the thermometer, not tradition.
5. 5

   Rest the roast

   Transfer the pork to a cutting board and tent loosely with foil. Rest for 20 minutes. This is not optional. The juices must redistribute throughout the meat. If you carve immediately, those juices will run onto the board instead of staying in the meat where they belong.

   The internal temperature will rise another 5 to 10 degrees during resting. This carryover cooking is why you remove the roast at 145°F, not higher.
6. 6

   Make the pan sauce

   While the meat rests, place the roasting pan over medium heat. If the pan juices have evaporated too much, add a splash of water or wine. Scrape up any browned bits from the bottom. Simmer briefly until slightly reduced. Taste and adjust salt. This is not a thick sauce. It is the concentrated essence of the roast.

7. 7

   Carve and serve

   Carve the roast into slices about half an inch thick, cutting between the rib bones if bone-in. Arrange on a warm platter and spoon the pan juices over. Arista may be served warm, at room temperature, or even cold the next day. In Tuscany, it is often prepared ahead and sliced for antipasto. The flavors deepen as it sits.

Chef Tips

• •Buy your pork from a butcher who can tell you where it came from. Heritage breeds like Berkshire or Duroc have more fat marbling and deeper flavor than commodity pork. The difference is substantial.
• •Arista is traditionally served at room temperature, which makes it ideal for entertaining. Roast it in the morning, let it rest, slice it before your guests arrive. The flavors are clearer when not piping hot.
• •The pan juices are precious. If they threaten to burn during roasting, add a few tablespoons of water to the pan. Burnt drippings make bitter sauce.
• •Leftover arista makes exceptional sandwiches. Slice thin, pile on crusty bread, drizzle with olive oil, and add nothing else. Perhaps some arugula if you must.

Advance Preparation

• •Season the meat with the rosemary-garlic paste up to 24 hours ahead. Cover and refrigerate. The flavors will penetrate more deeply.
• •Arista can be roasted up to one day ahead and served at room temperature. Refrigerate after cooling, then bring to room temperature before serving.
• •The cooked roast keeps well for 4 days refrigerated. Slice cold for sandwiches or antipasto.
