O.T.C Chowder/Oyster Cracker, 10 Ounces - What sets apart O.T.C from any other oyster cracker is their firm texture. The secret lies in the time consuming preparation and baking. The dough is given hours to rise naturally. Then it is kneaded and layered over and over. The crackers are stamped in rounded form and baked very slowly. So you get crackers that are crisp and crunchy all the way through.
