Description/Taste
Blue pumpkins vary in size, shape, texture, and flavor, depending on the variety. Most Blue pumpkins are medium to large varietals averaging 15 to 25 centimeters in diameter. The varieties range in shape from round and slightly flattened, ovate, to blocky with somewhat square shoulders and a flat base. The rind can be thick to thin with varying degrees of a smooth, firm, and taut surface to a bumpy texture with prominent ridging. Blue pumpkins will also display a gradient of color tones comprised of blue, green, and grey hues. Underneath the surface, the thick flesh is typically bright to dark orange and has a dense, slippery, and hard nature. The flesh also encases a central hollow cavity filled with stringy orange fibers suspending flat, oval, and cream-colored seeds. Blue pumpkins release a vegetal and sweet aroma when sliced and are most commonly utilized in cooked preparations. Some Blue pumpkin varieties can be eaten raw, but consumers generally prefer the mild, rich, and sweet flavor of the cooked pumpkins along with their stringless, smooth, and dry texture.
Seasons/Availability
Blue pumpkins are available in the fall through winter.

There are many different types of Blue pumpkins cultivated worldwide, found in varying sizes, shapes, and coloring, and the pumpkins are utilized as ornamental decoration or as a cooking ingredient. Blue pumpkins are native to the Americas and are one of the rarest pumpkin colorings. The pumpkin's blue-grey, sometimes green, tone is a natural genetic trait developed through traditional crossbreeding and hybridization techniques. It is important to note that the pumpkins are not genetically modified.

Blue pumpkins are also baked into scones, pies, brownies, and cakes, simmered into a puree for use as a dessert filling, added to pancake batter, quiche, and dips, or caramelized and served as a sweet.

Ethnic/Cultural Info
Blue pumpkins are a beloved culinary variety throughout Australia. Pumpkin seeds were carried from the Canary Islands, with the first wave of colonizers sent from Europe to Australia in 1788. The settlers suffered several years of poor food rations before establishing designated farmland in 1795, allowing various New World vegetables, including pumpkins, to grow. Historically, pumpkins were one of the primary food sources and were valued for their extended storage capabilities, large size, and versatile flavor. Pumpkins have remained a culinary staple throughout Australia, and in the modern day, they are notably used in pumpkin soup. Experts believe that the creamy dish has been made in Australia since at least the late 19th century. There are many variations of pumpkin soup among chefs and home cooks throughout the continent, and the soup is served in high-end restaurants, pubs, grocery stores, and as a pre-packaged meal. Queensland Blue pumpkins are a blue-skinned varietal often used in pumpkin soups. The variety's smooth, dry flesh is naturally used as a thickener in the soup, and its sweet flavor lasts throughout the cooking process, giving the dish a distinct taste.
Geography/History
Pumpkins are native to the Americas and were believed to have been domesticated as early as 7000 to 5000 BCE. Pumpkin remains found in Oaxaca, Mexico, reveal that there were varieties of pumpkins distinct from wild pumpkins, indicating that civilizations had been selectively breeding the vining plants. The original pumpkins descended from the wild types look different from those grown today, and the varieties were spread further into North America through migrating peoples. Spanish and Portuguese explorers also carried pumpkin seeds from the New World back to the Old World, where the seeds were planted in port cities. Pumpkin seeds were also planted throughout Europe and Asia, where new varieties were naturally crossbred by farmers and scientists to create improved cultivars. Blue pumpkins are descendants of varieties from the Americas and reached the height of their production in the 20th century. Today Blue pumpkins are found on every continent except for Antarctica. Blue pumpkins are primarily found in local markets through specialty growers when in season and are sold as a novelty for culinary and ornamental purposes.
