  Though mustard seed, cinnamon, peppercorn, allspice and bay leaves are the essential ingredients of pickling spice, other spices are often added to enhance its flavor. Whole cloves, ginger, mace, dill seeds, coriander seeds, juniper berries, cardamom and red pepper flakes can be added, depending on taste.
