The future of Pittsburgh’s classic Clark Bar remains in limbo, the Pittsburgh Post-Gazette reported. The family owned investment company that saved Twinkies and last month bought the New England Confectionery Co. — the Massachusetts-based maker of Necco Wafers, Clark Bars and other nostalgic candies — isn’t commenting on whether it will continue making the crunchy chocolate-covered peanut butter concoction created a century ago in Pittsburgh. The Metropoulos family picked up Necco for $17.3 million in bankruptcy court after the initial winning bidder, Ohio-based Spangler Candy Co., failed to close on its $18.83 million offer.
