{"type":"firestarter.listing","listing":{"id":"lst_LDPdjSUd","product_name":"Black Futsu Squash","category":"Vegetables","description":"Black Futsu is an heirloom Japanese pumpkin with attractive, deeply ribbed, bumpy skin that cures from deep black-green to a warm orange buff color. Its skin is thin and edible, and its flesh is top-notch: finely textured and extraordinarily nutty in flavor. It is wonderful roasted, fried in tempura, pureed in pies or soups, or pickled.\nWe like to imagine this squash as a metaphor of sorts: that no matter how complex and intricate something (or someone!) seems on the outside, it can be made up of sweet and simple truths.\nBlack Futsu bears 3-5 fruits per plant, averaging 3 lbs. each.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/files/IMG_3944.jpg?v=1736887956","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Black-Futsu-Squash-vendor-unknown-1630681194.jpg?v=1736887956","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Black-Futsu-Squash-vendor-unknown-1630681191.jpg?v=1736887956","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/IMG_6702.jpg?v=1736887956","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Black-Futsu-Squash-vendor-unknown-1630681200.jpg?v=1736887956","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Black-Futsu-Squash-vendor-unknown-1630681197.jpg?v=1736887786"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.401Z"},"share_url":"https://firestarter.network/l/lst_LDPdjSUd","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
