Real bacalao is expensive because it is essentially cod jerky. Cod, once a poor man's fish, is now pretty pricey. Shrinking a big piece of fish down into a small, salty piece makes it much more dear.
Caputo's is a fine source for real North-Atlantic salt cod that is not so old as to be ossified. I'd have some questions about what exactly the fish is at H-Mart -- not that they are misrepresenting anything, mind you, but there are many salted and dried fish, particularly in Asian markets.
Bacalao has a very strong and complex role in Southern European cooking, and an especially interesting (for me) place in the cooking of Latin America (probably also other former Iberian colonies in Asia and Africa). It was and remains a special thing that links Brazil, Cuba, etc. to the old country. I'd say it's a special occasion, luxury ingredient in much of Latin America, and has been for some time. I guess it's all relative, since the same has been true regarding things like canned fruit.
The classic Cuban prep is to mix soaked salt cod with chunks of potatoes, that have been first pan fried in olive oil, along with onions and garlic. Or one can make it "red" with a sofrito.
A basic Portuguese version is similar with chickpeas, onions and perhaps parsley.
Bacalao fritters/croquetas are common enough. And don't forget brandade.
I like my bacalao on the salty side, and I use it like anchovy to season other things, but many prefer for it to be completely rehydrated.
I'm sure this is a topic of great interest to Antonius, and I would like to see his thoughts on the best salt cod preps from Italy.
[Of course, while my computer slowly posted the above, Antonius was on it already.]
