I always assumed Black Cod was a type of cod, but it’s actually in a wholly different fish family! Black Cod is a bright white fatty fish with a very silky texture. It’s really buttery and silky and practically falls apart when you cut it. Black cod might also be called Sablefish or Butterfish, and it ranks very well in terms of sustainability. Cod is a white, meaty, flaky fish with a firm texture. You can actually use it in this recipe, but it’s definitely a different fish experience.
