This bright, crunchy salt enhances the natural flavors of any dish, adding the perfect touch of texture and depth.\nSlowly solar-evaporated and hand-processed without additives or heavy machinery, our finishing salt is a true expression of West Virginia’s rich salt-making heritage. Our salt contains naturally occurring amounts of magnesium, potassium, and calcium, along with many other trace minerals. Our salt is also free of microplastics and heavy metal contamination. Sprinkle it over grilled meats, roasted vegetables, fresh-baked bread, or even sweet treats like chocolate and caramel for a gourmet touch.\nIngredients: 100% Hand-Harvested Salt\nUses: Finishing, seasoning, baking, and cooking\nOrigin: Malden, West Virginia\nGrain size: Medium\n \n \n \n \n ","images":["https://cdn.shopify.com/s/files/1/0021/4771/3059/files/DSC4027.jpg?v=1759258794","https://cdn.shopify.com/s/files/1/0021/4771/3059/files/DSC6087-2.jpg?v=1773329915","https://cdn.shopify.com/s/files/1/0021/4771/3059/files/DSC4033-min.jpg?v=1773329915","https://cdn.shopify.com/s/files/1/0021/4771/3059/files/DSC4080-2-min.jpg?v=1773329915","https://cdn.shopify.com/s/files/1/0021/4771/3059/files/DSC4023-3_f32cddc3-c3a1-42d0-a7e2-e6c9dd9617b2.jpg?v=1773329915"],"price":6.5,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:11.410Z"},"share_url":"https://firestarter.network/l/lst_S0Xra-fX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
