Sea Best, the flagship brand of Jacksonville, Fla.-based Beaver Street Fisheries Inc., is expanding its popular value-add Signature product line with the introduction of a new entrée (Lobster Au Gratin) and the launch of Signature Singles (single-serve, gourmet, on-the-go meals that can be prepared in as little as four minutes). The microwavable entrée choices include citrus scallops and linguini, stuffed clams, black bean and shrimp tacos, tilapia Florentine, and spinach and artichoke flounder. The Signature Lobster Au Gratin entrée features lobster over creamy potato cakes, drizzled with a cheese and herb sauce. The portion includes two servings that can be prepared in the microwave or oven. The Signature Singles products originally were developed for convenience store sales, allowing customers to have gourmet seafood options that are individually sized and can be quickly prepared in a heat-and-serve microwaveable tray.
