{"type":"firestarter.listing","listing":{"id":"lst_NkW1q-ld","product_name":"Marionberry Jam - Reserve Collection","category":"Reserve Collection","description":"The jewel of the Pacific Northwest, marionberries are prized for their deep color and naturally complex flavor, which is a balance of sweet, tart, and earthy notes that makes them stand out from ordinary blackberries. Our marionberry jam captures all of that richness in a jar, perfect for spreading on warm biscuits, swirling into yogurt, or pairing with sharp cheeses.\nThis jam is part of our Reserve Collection—a small batch series inspired by customer requests and made with premium fruit that’s harder to find and more work to process. You’ll taste the difference!","images":["https://cdn.shopify.com/s/files/1/1624/3371/files/H5X2352.jpg?v=1756616710","https://cdn.shopify.com/s/files/1/1624/3371/files/Marionberry_1.png?v=1761112817","https://cdn.shopify.com/s/files/1/1624/3371/files/Marionberry_2.png?v=1761112817","https://cdn.shopify.com/s/files/1/1624/3371/files/Marionberry_3.png?v=1761112817"],"price":11,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:11.871Z"},"share_url":"https://firestarter.network/l/lst_NkW1q-ld","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
