Seabass fillet is a cut of fish from the sea bass with a stout body and a white belly. Sea bass fillets are known for their firm, white flesh, delicate, flaky texture and mild, sweet flavor. They can be slightly oily and fatty, with a texture that’s silky yet a little chewy. Seabass fillets are versatile and can be used in a variety of dishes, pairing well with both strong spices and garden herbs.
