I don't know. Waverly Root asserts, in Eating in America (1976), that it is a distant forth among American meats, and that the average american only eats four pounds of it a year. It has something to do, I think, with the historically timid palates of Americans. Lamb has a distinct taste, and that in itself is enough to put off a lot of people, who prefer skinless chicken breasts and filet of sole to meats that know their own mind. Lamb is pretty popular overall; what strikes me is why people don't eat more mutton. Lamb is a pallid version of mutton, and resembles its rank majesty only as much as a game hen does a full-bodied roaster. I think, too, that lamb has been under-utilized by cooks. When people think of lamb they think of lamb chops and leg of lamb. Lamb chops are relatively expensive, and of course the contemporary obsession with fat causes them to "frenched" by butchers, which makes them hardly worth eating. Leg of lamb, meanwhile, is an old-time classic, but only when made carefully in a slow oven. Just popping a leg of lamb into an oven won't get you far, and it will be chewy if you overcook it. Finally, I think that the relative obscurity of lamb can be accounted for not by any of its own deficiencies, but rather by the comparative excellence of beef and pork. Cattle are really the perfect meat animal, and it was our country in which beef production on a truly vast scale, of the kind never imagined in the old world, enabled every man, woman, and child to enjoy the bounty of fresh beef every day. And the humble pig, of course, which eats garbage or even forages for itself, and then gives to the world a hundred tasty kinds of meat, will always be the staple meat of family farms. Just like movies, cars, gunnery, and so many other european inventions, beef and pork were taken by the American genius to unforeseen heights, and lamb was left behind. People still like it, esp. Greek-americans, but it never found its way into the starry dynamo of American development, and remains a backwater in the land of meat. yrs, Mr. Cutlets
