About Chilean sea bass[]
Chilean sea bass is not interchangeable with other bass. If you can't find it, cod is a closer substitute than a different type of sea bass. Chilean sea bass has a very different texture from that of other fish. Even when it is cooked to well-done, the remains soft. Since it doesn't firm up, you'll need to check its temperature to tell whether it's done. Stab a small bamboo stick into the middle of the fillet. Leave for a moment, pull it out and touch the end. If it's hot, the is ready.
