The chefs battling for the title of Maine Lobster Chef of the Year came to the Ocean Gateway Terminal on Friday armed with a wide array of delicious ingredients – butter-poached lobster, bacon, sweet corn and Cognac. In the end, it was Stephen Richards, chef at The World is Mine Oyster in Boothbay Harbor, who took home the honor and a big $1,000 check presented by emcee Kerry Altiero, owner of Cafe Miranda in Rockland and a past winner of the contest. “Man, what a day,” a breathless Richards told the sold-out audience of 200 who voted on the outcome along with four professional judges.
