{"type":"firestarter.listing","listing":{"id":"lst_FK0E8vHv","product_name":"Blue Hubbard Squash","category":"Vegetables","description":"This is our favorite Thanksgiving squash. We slice it in half, bake it in the oven and stuff it with a nutty brown rice pilaf. The 15-30 pound fruit makes an amazing main dish and centerpiece to the meal. The indelicacy of the shape, warts and all, is balanced by the bright orange flesh and and fine-textured sweet taste that melts in your mouth. Blue Hubbard is also an excellent keeper, lasting until early spring.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Blue-Hubbard-Squash-vendor-unknown-1630675272.jpg?v=1735580487","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Blue-Hubbard-Squash-vendor-unknown-1630675274.jpg?v=1735580487","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Blue-Hubbard-Squash-vendor-unknown-1630675278.jpg?v=1735580487","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Blue-Hubbard-Squash-vendor-unknown-1630675282.jpg?v=1735580487"],"price":20.39,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:40.010Z"},"share_url":"https://firestarter.network/l/lst_FK0E8vHv","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
