I'm not sure I have a favorite. Let me give you an overview.
My got to steak would be a ribeye but I've been ordering filet mignon because it is smaller.
Strip steaks are good in a pinch.
I get boneless spare ribs to make stews
I've always got veal shanks in the freezer for a nice osso buco.
I love lamb. My mother used to make lamb fritters but I never got the recipe from her. She would put the lamb in a port of water and cook until it was tender. I don't know what cut she used or what she seasoned it with. Once cooled and shredded it was mixed into a pancake-like batter and fried up. It was one way to divide our family - those that loved the fritters and those that hated them. This is one of the reasons I married my wife - she loved them.
Lamb chops - any kind
Rack of lamb
Roast leg of lamb.
I Love a good pork chop. Particular favorite is the "porterhouse" style but loin chop in a pinch.
The tenderloins are so versatile. I grill them, cut-and-pound them pan fry and make schnitzel, pork parm, etc.
I made pork osso buco once. It was delicious and maybe a little too rich.
Ham, roast or smoked pork - Bring it on.
I'm clearly a dark-meat person. I would rather have a leg or thigh than breast meat. Regardless if it is roasted, grilled, stewed.
Nothing like a good duck breast.
