Yield: 4 servings
Total time: At least 2 1/2 hours
1. Combine the lamb shanks, Port or wine, and garlic in a skillet just large enough to hold the shanks. Turn the heat to high and bring to a boil; cover and turn the heat so that the mixture simmers gently. Cook, turning about every 30 minutes, until the shanks are tender and a lovely mahogany color, at least 2 hours and more likely longer.
2. Remove the shanks and strain the sauce. If time allows, refrigerate both, separately; skim the fat from the top of the sauce. Preheat a charcoal or gas grill or the broiler; the rack should be 4 to 6 inches from the heat source, and the fire hot.
3. Grill or broil the shanks until nicely browned all over, sprinkling them with salt and pepper and turning as necessary; total cooking time will be about 15 minutes. Meanwhile, reheat the sauce gently; season it with salt and pepper, then add the vinegar or lemon juice. Taste and add more seasoning if needed. Serve the shanks with the sauce.
Variation: Anise-flavored Lamb Shanks (or Short Ribs)
Braise the meat in a mixture of 1/4 cup soy sauce, 1 cup water, 5 thin slices of ginger, 5 whole star anise, 4 cloves garlic, and 1 tablespoon sugar. Proceed as above, finishing the sauce with rice or white wine vinegar.
Richard Wrangham, a professor at Harvard University and author of Catching Fire, studies the role of cooking in human evolution. "Once you start thinking about the importance of cooking -- its supply of energy, its strange distribution compared to natural foods -- it's bound to have affected our evolution hugely, our behavior, our society, our cognition, all sorts of features about us," he says.
