Salt potatoes

Salt potatoes are a regional dish of Syracuse, New York, typically served in the summer when the young potatoes are first harvested. They are a staple food at fairs and barbecues in the Central New York region, where they are most popular. Potatoes specifically intended for salt potatoes can be purchased by the bag along with packages of salt. As the potatoes cook, the salty water forms a crust on the skin, and the higher boiling temperature allows the starch in the potato to cook more completely, giving a creamier texture. The Syracuse area of New York has a long history of salt production. Brine from salt springs located around Onondaga Lake was used to create consumable salt that was distributed throughout the northeast via the Erie Canal. Salinated brine was boiled dry in large vats known as "salt blocks", and the salt residue was then scraped up, ground, and packaged.
