Pernod is the classic anise-flavored liqueur used in combination with oysters in many Creole New Orleans recipes, such as oysters Rockefeller. Herbsaint or absinthe can be substituted. Basil adds a fresh herbal note to this dish; be sure to include it. You can buy Louisiana oysters online in the 1-pound (approx. 2 dozen oysters), vacuum-sealed Vermilion Bay Sweet brand package sold at the
Louisiana Direct Seafood SHOP website. These are high-quality, fat, juicy oysters that are flash-frozen at their peak of freshness.
