Gone and Mostly Forgotten

Tripe

Has anyone noticed that the selections of meat and offal offerings at your local supermarket  are getting much more narrow? I have and it's beginning to bug me. Many of the meats that I have enjoyed are just not to be found. I suspect it might be that our younger generations don't know how to prepare many of these items and they thus go unsold. Here are a few of those that I sorely miss:

Fresh ham (not smoked!), sweetbreads (thymus' are better), pale calf's liver, capons (chicken or turkey), chicken hearts (in bulk), hanger steak, pork chops (with fillets included), Porterhouse steaks, beef neck meat (makes the best hamburgers), real dried beef, trit-tip steaks (other than on the West Coast), pigs' knuckles, tripe (beef or pig stomach), breast of lamb, pork crown roast, veal cheeks, real prime beef rib roast ... even lamb shanks are getting increasingly rare.

I've gone on the Internet trying to find many of these items. Slim pickings!
