This was a happy surprise! It doesn't sound like much, but it's easy, tasty, and you can certainly serve it to company.
The original recipe calls for Hake, but finding hake is pretty hit-or-miss in these parts. It's a local fish, but it's not always pretty and it's not well-known, so many fish markets don't carry it. But cod cooks up about the same, maybe a little bit slower for a fat loin, so it's an easy substitution for this worthy recipe.
