Cooked down with pure cane sugar and just a touch of citrus pectin, this jam captures that bright, juicy flavor in every spoonful.\nIt’s versatile, vibrant, and just the thing for toast, cheese boards, or a quick spoonful straight from the jar.","images":["https://cdn.shopify.com/s/files/1/1624/3371/files/santa-rosa-plum-jam-870928.jpg?v=1762457283","https://cdn.shopify.com/s/files/1/1624/3371/files/santa-rosa-plum-jam-962204.jpg?v=1715613487"],"price":9,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:12.009Z"},"share_url":"https://firestarter.network/l/lst_mg4QX1ut","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
