Hello,
I currently live in Beijing and I never would have thought to try this cut unless I was in China, where it's probably the most common cut of beef you can find everywhere. The meat grocer was almost out of every other kind of beef, so I asked for an end piece of the shank, about the size of a fist. It didn't look like much, pure red with not a speck of savory fat or stock-enhancing bone, streaked with inedible-looking white tissue, as tough and surly as the meat grocer's attitude, but I didn't really have a choice.
I did my usual routine, frying the onions, peppers, spices, and what little ground beef I had in the main pot and in a seperate pan I browned the shank piece in vegetable oil, deglazed with some Tsingtao beer, and added it to the main pot when I reached the simmer stage. Three hours later I went to stir the pot and the shank just fell apart into tender chunks and strands. I have never made a pot of chili so thick and rich. Whatever cooked out of that shank made this the best chili I have ever made. And it's cheap too!
I used to obsess about hunting down tri-tip to grind, or getting the coarseness and fat content just right, or mixing various concoctions of ground meat from different animals, but no more! I think next time I will cut the shank into smaller pieces before browning, and skip the ground meat altogether. (Random thought: I wonder if you could slow-smoke a beef shank? Hm..) Chili weather is more or less over, but give it a try when you get the chance!
