Fall Harvest: Pumpkins

Several large pumpkins

Pumpkins are the most common winter squash and come into season in September in most areas.




Pumpkin refers to certain cultivars of squash, most commonly those of Cucurbita pepo, that are round, with smooth, slightly ribbed skin and deep yellow to orange coloration. The thick shell contains the seeds and pulp. Some exceptionally large cultivars of squash with similar appearance have also been derived from Cucurbita maxima. Specific cultivars of winter squash derived from other species, including C. argyrosperma, and C. moschata, are also sometimes called "pumpkin". In Australian English, the term "pumpkin" generally refers to the broader category called winter squash elsewhere.
Pumpkins, like other squash, are native to North America. Pumpkins are widely grown for commercial use, and are used both in food and recreation. Pumpkin pie, for instance, is a traditional part of Thanksgiving meals in the United States, although commercially canned pumpkin puree and pumpkin pie fillings are usually made from different kinds of winter squash than the pumpkins frequently carved as jack o'lanterns for decoration around Halloween.






Pumpkins, like other squash, are thought to have originated in North America. The oldest evidence, pumpkin-related seeds dating between 7000 and 5500 BC, were found in Mexico.
Since some squash share the same botanical classifications as pumpkins, the names are frequently used interchangeably. One often used botanical classification relies on the characteristics of the stems: pumpkin stems are more rigid, prickly, and angular (with an approximate five-degree angle) than squash stems, which are generally softer, more rounded, and more flared where joined to the fruit.

Traditional C. pepo pumpkins generally weigh between 6 and 18 pounds (2.7 and 8.2 kg), though the largest cultivars (of the species C. maxima) regularly reach weights of over 75 pounds (34 kg).
The color of pumpkins is derived from the orange pigments abundant in them. The main nutrients are lutein and both alpha and beta carotene, the latter of which generates vitamin A in the body.






The largest pumpkins are Cucurbita maxima. They were cultivated from the hubbard squash genotype, crossed with kabocha-pumpkin types by enthusiast farmers through intermittent effort since the early 19th century. As such germplasm is commercially provocative, a U.S. legal right was granted for the rounder phenotypes, levying them as constituting a variety, with the appellation Atlantic Giant. Eventually, this phenotype graduated back into the public domain, except now it had the name Atlantic Giant on its record (see USDA PVP # 8500204).
Weigh-off competitions for giant pumpkins are a popular festival activity. The world record held at 459 pounds (208 kg) until 1981, when Howard Dill (of Nova Scotia) broke the record with a pumpkin weighing 493.5 pounds (223.8 kg). Dill patented the seeds used to grow this giant pumpkin, deeming them Dill’s Atlantic Giant seeds, and drawing growers from around the world. Dill is credited for all of the giant pumpkins today, most of which are borne from crossing and re-crossing his patented seed with other varieties. By 1996, giant pumpkins had crossed the 1,000-pound (450 kg) mark. The current world record holder is Ron Wallace's 2,009.0-pound (911.3 kg) Atlantic Giant pumpkin, which in September 2012 surpassed Jim and Kelsey Bryson's previous 2011 record of 1,818.5 pounds (824.9 kg).

Pumpkin pie is a popular way of preparing pumpkin.

Pumpkins are very versatile in their uses for cooking. Most parts of the pumpkin are edible, including the fleshy shell, the seeds, the leaves, and even the flowers. In the United States and Canada, pumpkin is a popular Halloween and Thanksgiving staple. Pumpkin purée is sometimes prepared and frozen for later use.
When ripe, the pumpkin can be boiled, baked, steamed, or roasted. In its native North America, it is a very important, traditional part of the autumn harvest, eaten mashed and making its way into soups and purees. Often, it is made into pie, various kinds of which are a traditional staple of the Canadian and American Thanksgiving holidays. In Canada, Mexico, the United States, Europe and China, the seeds are often roasted and eaten as a snack.
Pumpkins that are still small and green may be eaten in the same way as squash or zucchini. In the Middle East, pumpkin is used for sweet dishes; a well-known sweet delicacy is called halawa yaqtin. In South Asian countries such as India, pumpkin is cooked with butter, sugar, and spices in a dish called kadu ka halwa. Pumpkin is used to make sambar in Udupi cuisine. In Guangxi province, China, the leaves of the pumpkin plant are consumed as a cooked vegetable or in soups. In Australia and New Zealand, pumpkin is often roasted in conjunction with other vegetables. In Japan, small pumpkins are served in savory dishes, including tempura. In Myanmar, pumpkins are used in both cooking and desserts (candied). The seeds are a popular sunflower seed substitute. In Thailand, small pumpkins are steamed with custard inside and served as a dessert. In Italy, it can be used with cheeses as a savory stuffing for ravioli. Also, pumpkin can be used to flavor both alcoholic and nonalcoholic beverages.
In the southwestern United States and Mexico, pumpkin and squash flowers are a popular and widely available food item. They may be used to garnish dishes, and they may be dredged in a batter then fried in oil. Pumpkin leaves are a popular vegetable in the Western and central regions of Kenya; they are called seveve, and are an ingredient of mukimo, respectively, whereas the pumpkin itself is usually boiled or steamed. The seeds are popular with children who roast them on a pan before eating them.
Commercially canned "pumpkin" puree and pumpkin pie fillings are often made with winter squashes other than the traditionally defined pumpkin, such as butternut squash.






Pumpkin seeds, also known as pepitas, are small, flat, green, edible seeds. Most pumpkin seeds are covered by a white husk, although some pumpkin varieties produce seeds without them. Pumpkin seeds are a popular snack that can be found hulled or semi-hulled at most grocery stores. However, roasting pumpkin seeds (usually scooped out of jack-o-lanterns) is a popular Halloween treat. Per ounce serving, pumpkin seeds are a good source of protein, magnesium, copper and zinc.

Canned pumpkin is often recommended by veterinarians as a dietary supplement for dogs and cats that are experiencing certain digestive ailments such as constipation, diarrhea, or hairballs. The high fiber content helps to aid proper digestion.
Raw pumpkin can be fed to poultry, as a supplement to regular feed, during the winter to help maintain egg production, which usually drops off during the cold months.
Pumpkin phytochemicals and nutrients remain under preliminary research for potential biological effects.






Pumpkins are commonly carved into decorative lanterns called jack-o'-lanterns for the Halloween season in North America. Throughout Britain and Ireland, there is a long tradition of carving lanterns from vegetables, particularly the turnip, mangelwurzel, or swede. The turnip has traditionally been used in Ireland and Scotland at Halloween, but immigrants to North America used the native pumpkin, which are both readily available and much larger – making them easier to carve than turnips. Not until 1837, does jack-o'-lantern appear as a term for a carved vegetable lantern, and the carved pumpkin lantern association with Halloween is recorded in 1866.
In the United States, the carved pumpkin was first associated with the harvest season in general, long before it became an emblem of Halloween. In 1900, an article on Thanksgiving entertaining recommended a lit jack-o'-lantern as part of the festivities that encourage kids and families to join together to make their own jack-o'-lanterns.
