Ingredient

Beef short rib

Rib bones with a thick cap of well-marbled meat, sold cut across the bone (flanken) or along it (English). The bone and the collagen do the work: a long braise gives you a sauce with body you cannot get from a leaner cut.

Sourcing
A butcher will cut them either way — say which you want. Korean grocers sell flanken-cut ribs ready for grilling.
Varieties
English cut, Flanken cut, Boneless
Quality cues
A generous, even meat cap over the bone. Ribs that are mostly bone with a thin skim of meat are poor value however cheap.
Substitutions
Beef chuck, Beef shin, Oxtail
Storage
Refrigerate at 4°C or below, bottom shelf. Braise, cool and refrigerate overnight if you want to lift the fat off easily.
Shelf life
3-5 days refrigerated raw; 6-12 months frozen
