{"type":"firestarter.listing","listing":{"id":"lst_qdxbV5ut","product_name":"French Grey Sea Salt (Sel Gris)","category":"Salts","description":"\nSel Gris is a moist, coarse salt harvested from the Atlantic. It's perfect to keep at the table in a tiny bowl for sprinkling on fresh tomatoes, buttered bread and meat.\n\"French grey salt is harvested from the clay-lined bottom layer of salt flats where it picks up minerals and obtains its characteristic silvery color. I love grey salt for its versatility: it works equally well as a cooking or a finishing salt, since it is fine enough to dissolve easily, and granular enough to add a little texture. Moist and briny, sel gris invites the ocean to your table.\" - Clare's Staff Picks, 2020","images":["https://cdn.shopify.com/s/files/1/0604/1077/products/French_Grey-Square-0417.jpg?v=1621976806"],"price":8.75,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:11.084Z"},"share_url":"https://firestarter.network/l/lst_qdxbV5ut","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
