1Prepare the large globe artichokes: Trim the tough outer leaves until only the tender, pale green inner leaves remain. Cut off the top third of each artichoke. Using a spoon, scoop out the fibrous choke from the center. Rub all cut surfaces immediately with a half lemon to prevent discoloration. Place the prepared artichokes in a bowl of cold water with the remaining lemon juice.
2Prepare the stuffing: In a large bowl, combine the stale breadcrumbs, grated Pecorino Romano, minced garlic, chopped fresh parsley, finely diced pancetta, 30 grams of extra-virgin olive oil, the large egg, 3 grams of fine sea salt, and black pepper. Mix thoroughly with your hands until well combined and slightly moist.
