While the lamb roasts, pile the romaine leaves on a platter, cover, and refrigerate serving. Place the salt, cumin, Aleppo pepper, honey, and lemon wedges in small individual bowls to pass at the table. Pile the mint, watercress, and cilantro on a plate, cover, and refrigerate.
When the lamb is about 10°F (12°C) below the final desired doneness, turn on the broiler. (Because the acids in the marinade slow down browning, a finish of a fast broil is needed to make the lamb all burnished and becoming.) Broil until crusty, about 5 minutes. Turn the meat and repeat. Transfer the lamb to a platter and let rest at room temperature for 10 to 15 minutes so the juices can settle and the meat can rise to its final temperature.
While the lamb rests, make the pan sauce by placing the roasting pan over two burners cranked to high heat. Stir in the wine, scraping the bottom of the pan as you bring the pan juices to a boil. Cook, stirring, until the sauce is thick and rich tasting, about 2 minutes. Reduce the heat to low to keep the sauce warm.
Thinly slice the lamb across the grain and arrange the lamb on a platter. Pour the pan sauce over the lamb, garnish with a few sprigs of the herbs, and place it on the table along with romaine, spices, honey, lemon, herbs, and so forth. Instruct guests to roll the lamb in the romaine along with the spices, honey, herbs, and a squeeze of lemon.
