Salt cod (or, more accurately, saltfish, because it’s often a cod-relative, or even a different species altogether), may no longer be a staple for many people, but it’s sold in loads of supermarkets and is often quite inexpensive. The fish—called morue (French), baccalà (Italian), bacalao (Spanish), bacalhau (Portuguese), and more—often comes in wooden boxes, sometimes in large slabs of half a fish.
