Made with stone ground cornmeal. Old Fashioned Quality & Goodness: Each package of Kenyon's Clam Cake Mix is manufactured in our century old grist mill, using only the finest ingredients to provide you with the quality product you deserve. A full pound box of clam cake mix is made with no additives or preservatives and must be kept cool to ensure freshness. Each year in September the folks at Kenyon's travel to the Eastern States Exposition in Springfield, Massachusetts, where we cook Rhode Island's famous Johnny Cakes, and our popular Clam Cakes and Chowder. You can also catch us at various local fairs & festivals during the summer. At home you can enjoy the same light, tender, non-grease Kenyon's Clam Cakes.
