Hey kiddo, do you know what beef is? It's a type of meat that comes from cows. Now, a beef shank is a part of the cow that's located above the leg.
Imagine the cow's leg, and then imagine a big chunk of meat that's still attached to the leg bone. That's what a beef shank is.
Beef shanks are tough because they come from a part of the cow that's used a lot. But they have lots of flavor! So, people often cook them for a long time on low heat to make them tender.
Some people make beef shank soup or stew, and others might braise them (that means cooking them slowly in liquid, like red wine) until they're fall-apart tender.
Beef shank might not be the most glamorous cut of meat, but it's delicious when cooked right!
