Like sardines, kippers aren’t born kippers – they become kippers through a special processing method. Becoming a King Oscar Kipper Snack is tougher still. We use only premium quality fillets of herring, sustainably wild-caught in the North Atlantic, in waters specially certified by the Marine Stewardship Council (MSC). Non-GMO Project Verified. The high oil content of these clupea harengus fish yields a superior taste during our time-tested traditional salting and light smoking process. Speaking of which, we always authentically wood-smoke our fish, and never use artificial, chemical flavoring. Our Kipper Snacks are delicious straight from the can on toast or crackers, or in fisherman’s eggs.
