Beef shin is a cheap but tasty cut commonly used in casseroles, curries, and hotpots. It comes from the foreshank of a cow, and as this is a hard-working muscle it has lots of tough connective tissues. However, if cooked low and slow, these fibres break down and in doing so, thickens the sauce. So whilst a inexpensive cut because of the cooking time required, the results are well worth the wait.
