Wild caught Chilean sea bass, sold by the pound from the seafood counter. This premium fish, also known as Patagonian toothfish, features firm white flesh with a melt-in-the-mouth consistency and a delicate, buttery flavor profile similar to black cod. Each piece is hand-trimmed, boneless, and skinless.
This previously frozen product is MSC Certified Sustainable Seafood, ensuring responsible fishing practices. Thaw overnight in the refrigerator before cooking. Chilean sea bass is excellent pan-seared for a golden crust, poached for extra-tender results, or grilled with garlic butter. Once thawed, use within two days and do not refreeze.
