Cod
Cod is lean, mild, and built out of unusually large flakes, which is why it falls apart in a pan and holds together in batter. Nearly all cod sold in the US is now Pacific cod; the Atlantic fishery that made the fish famous collapsed in 1992 and has never recovered.
In one line
Black cod and lingcod are both sold as cod. Neither one is a cod.
Buy it if
You're battering and frying, roasting in a hot oven, or building a chowder — anywhere the big flake is a feature.
Pacific, not Atlantic. Gadus macrocephalus out of the Bering Sea and the Gulf of Alaska is what you are almost certainly buying. Atlantic cod (G. morhua) built and then broke the Newfoundland economy — Canada closed the Grand Banks fishery in 1992 in one of the largest fishery collapses ever recorded, and the stock has not come back.
Black cod and lingcod are not cod. Sablefish is sold as "black cod" and is a fatty, unrelated deep-water fish. Lingcod is a greenling. Neither behaves like cod in a pan and neither is priced like it.
Large flake plus no fat means it wants moisture or batter. Cod's muscle segments are big and loosely bound, with no fat holding them together, so aggressive dry heat makes it collapse. Roast it hot, poach it, or fry it in a batter that does the structural work.
Buy the loin, not the tail. The thick center cut cooks evenly. The thin tail end is already overdone by the time the loin is ready.

Cod vs Sablefish
Sablefish is sold as "black cod" and isn't a cod — the two are opposites in fat, price and how much they forgive.

Common questions
What temperature is cod done?
130–135°F. It reads as done when the flakes separate under gentle pressure but still look glossy rather than dry. Because the flakes are so large, cod signals doneness more clearly than most fish.
Is black cod the same as cod?
No, and they aren't related. "Black cod" is sablefish, a deep-water fish with several times the fat of a true cod — buttery where cod is lean, roughly twice the price, and nearly impossible to overcook. The name is marketing, and it has stuck for over a century.
Why does my cod turn to mush?
Water, usually, not heat. Cod holds a lot of it, so a crowded pan steams instead of searing and the flakes let go. Pat it very dry, use a pan wider than you think you need, and leave it alone once it's down.
Is frozen cod worse than fresh?
Usually better. Most Pacific cod is frozen at sea within hours of the catch. The "fresh" fillet in the case was very often frozen too, then thawed for you days ago — same fish, more time on it.
