Cape Cod Kettle Cooked Sea Salt & Vinegar Potato Chips Party Size, perfect for entertaining. Classic pairing of salty and tangy flavors is loved by so many (including us). So we challenged ourselves to come up with the perfect mouth-puckering recipe as a tribute - we found that the thick-sliced, robust potato taste of our kettle cooked potato chips called for a bit more vinegar than a thinner chip might hold. The result is a tangy, salty, sour taste delivered with a full, hearty crunch that people crave.
