An earth oven, ground oven or cooking pit is one of the simplest and most ancient cooking structures. The earliest known earth oven was discovered in Central Europe and dated to 29,000 BC. [1] At its most basic, an earth oven is a pit in the ground used to trap heat and bake, smoke, or steam food. Earth ovens have been used in many places and cultures in the past, and the presence of such cooking pits is a key sign of human settlement often sought by archaeologists. Earth ovens remain a common tool for cooking large quantities of food where no equipment is available.[ citation needed ] They have been used in various civilizations around the world and are still commonly found in the Pacific region to date.
To bake food, the fire is built, then allowed to burn down to a smoulder. The food is then placed in the oven and covered. This covered area can be used to bake bread or other various items. Steaming food in an earth oven covers a similar process. Fire-heated rocks are put into a pit and are covered with green vegetation to add moisture and large quantities of food. More green vegetation and sometimes water are then added, if more moisture is needed. Finally, a covering of earth is added over everything. The food in the pit can take up to several hours to a full day to cook, regardless of the dry or wet method used.
Today, many communities still use cooking pits for ceremonial or celebratory occasions, including the indigenous Fijian lovo, the Hawaiian imu, the Māori hāngī , the Mexican barbacoa, and the New England clambake.[ citation needed ] The central Asian tandoor use the method primarily for uncovered, live-fire baking, which is a transitional design between the earth oven and the horizontal-plan masonry oven. This method is essentially a permanent earth oven made out of clay or firebrick with a constantly burning, very hot fire in the bottom.
In many areas, archaeologists recognize "pit-hearths" as being commonly used in the past[ citation needed ]. In Central Texas, there are large "burned-rock middens" speculated to be used for large-scale cooking of plants of various sorts, especially the bulbs of sotol.[ citation needed ] The Mayan pib and Andean watia are other examples. In Mesoamerica and the Caribbean nations, barbacoa is a common practice.[ citation needed ] Barbacoa, originally a Taino word referring to the pit itself, consists of slow-roasted meat in a maguey-lined pit, popular in Mexico alongside birria, tortillas, and salsa.
The clambake, invented by Native Americans on the Atlantic seaboard and considered a traditional element of New England cuisine,[ citation needed ] traditionally uses a type of ad hoc earth oven (usually built on a beach). A large hole is dug into the sand and heated rocks are added to the bottom of the hole. A layer of seaweed is then laid on top to create moisture and steam, followed by the food. Finally, another layer of seaweed is added to trap in the steam and cook the food, which mainly consists of shellfish and vegetables.
The curanto of the Chiloé Archipelago consists of shellfish, meat, potatoes, milcao chapaleles, and vegetables traditionally prepared in an earth oven. It has spread to the southern areas of Chile.[ citation needed ]
The huatia or watia and pachamanca are traditional earth ovens of the Andean regions of Peru, Bolivia, and Chile. They are both indigenous practices that pre-date the Inca Empire.[ citation needed ]
In China, dishes such as beggar's chicken were originally prepared with earth ovens, where the inventor is said to have "dug a hole, lit a fire and buried the chicken." [2]
The Hakka of China that live in tulou have been known to use earth ovens to cook. [3]
In Taiwan, earth ovens (Chinese :炕窯) are also a popular way to cook. In early Taiwanese agricultural society, adults would take children to build earth ovens and cook simple ingredients like sweet potatoes and taro. [4]
Earth oven cooking is sometimes used for celebratory cooking in North Africa, particularly Morocco: a whole lamb is cooked in an earth oven (called a tandir, etymologically related to the Central- and South-Asian tandoor and possibly descended from an Akkadian word tinuru) in a manner similar to the Hawaiian kālua.[ citation needed ] Among Bedouin and Tuareg nomads, a simple earth oven is used – often when men travel without family or kitchen equipment in the desert.[ citation needed ] The oven is mostly used to bake bread but is also used to cook venison and waran. When baking bread, the wheat or barley flour is mixed with water and some salt and then placed directly into the hot sands beneath the camp fire. It is then covered again by hot coal and left to bake. This kind of bread is eaten with black tea (in the absence of labneh). The sand has to be knocked off carefully before consuming the bread. Sometimes this type of bread is also made when the family is together, because people like the taste of it. The bread is often mixed with molten fat (sometimes oil or butter) and labneh (goat milk yoghurt) and then formed into a dough before eating. This bread is known as Arbut [5] but may be known under other local names.
Earth oven cooking was very common in the past and continues into the present – particularly for special occasions, since the earth oven process is very labor-intensive.[ citation needed ]
In some part-Melanesian, Polynesian, and other closely related languages, the general term is "umu," from the Proto-Oceanic root *qumun (e.g. Tongan ʻumu, Māori umu or hāngī , Hawaiian imu, Samoan umu, Cook Island Māori umu).[ citation needed ] In some non-Polynesian, part-Polynesian, and Micronesian parts of the Pacific, which some islands use the similar word umu, but not all Micronesian islands having many different languages use that base word umu, however, other words are used instead of umu - in Fiji it is a lovo, in Rotuman it is a koua and in Tahiti, it is a ahima'a.[ citation needed ]
In Papua New Guinea, "mumu" is used by Tok Pisin and English speakers, but each of the other hundreds of local languages has its own word. In the Solomon Islands the word in Pidgin is Motu.[ citation needed ]
Despite the similarities, there are many differences in the details of preparation, their cultural significance, and current usage. Earth ovens are said to have originated in Papua New Guinea and have been adopted by the later arriving Polynesians.[ citation needed ]
The Samoan umu uses the same method of cooking as many other earth ovens and is closely related to the Hawaiian earth oven, the imu, which is made underground by digging a pit (although generally the umu is done above ground rather than in a pit).[ citation needed ] It is a common day-to-day method of preparing roasted foods, with modern ovens being restricted to western-style houses.[ citation needed ] In the traditional village house, gas burners will be used inside the house to cook some food in pots.[ citation needed ] The umu is sheltered by a roof in case of rain, and it is separate from the house. There are no walls, which allows the smoke from the umu to escape.[ citation needed ]
The Samoan umu starts with a fire to heat rocks which have been tested by fire as to whether they will explode upon heating. These rocks are used repeatedly but eventually are discarded and replaced when it is felt that they no longer hold enough heat. Once the rocks are hot enough, they are stacked around the parcels of food which are wrapped in banana leaves or aluminium foil. Leaves are then placed over the assembly and the food is left to cook for a few hours until it is fully cooked.[ citation needed ]
The Hawaiian imu was the easiest way to cook large quantities of food quickly and efficiently for the Hawaiians. Because their creation was so labor-intensive, imus were only created for special events or ceremonies where it would be worth the time and hard work. An imu is created by first digging a 2- to 4-foot hole in the ground. Porous rocks are heated for a while and subsequently added to the bottom of the pit; next, a layer of banana stumps is added on top of them along with banana leaves. After the vegetation is laid down, the meat, fish, and any other foods are placed on top and covered once again with more vegetation. Wet cocoa sacks are also sometimes added on top to add even more moisture and trap in more heat. [6]
In Europe, earth ovens were used from the Neolithic period onward, with examples from this period found at the sites of Rinyo and Links of Notland on Orkney, [7] but are more commonly known in the Bronze and Iron Ages from sites such as Trethellan Farm, Newquay and Maiden Castle, Dorset, and in Scandinavia.[ citation needed ] Many pot boilers from British prehistoric sites are now considered to be the by-product of cooking with stones, in something similar to a Polynesian oven. [8] Examples from the European prehistoric vary in form but are generally bowl-shaped and shallow in depth (30–45 cm), with diameters between 0.5 and 2 metres.
Exceptions do exist, such as the Irish Fulacht fiadh, in common use up to the Middle Ages. In Greek cuisine, there is also a tradition of kleftiko ("thief style") dishes, ascribed to anti-Turkish partisans during the Greek War of Independence, which involve wrapping the food in clay and cooking it in a covered pit, allegedly at first to avoid detection by Turkish forces.
Baking is a method of preparing food that uses dry heat, typically in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread, but many other types of foods can be baked. Heat is gradually transferred "from the surface of cakes, cookies, and pieces of bread to their center, typically conducted at elevated temperatures surpassing 300°F. Dry heat cooking imparts a distinctive richness to foods through the processes of caramelization and surface browning. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center. Baking can be combined with grilling to produce a hybrid barbecue variant by using both methods simultaneously, or one after the other. Baking is related to barbecuing because the concept of the masonry oven is similar to that of a smoke pit.
Grilling is a form of cooking that involves heat applied to the surface of food, commonly from above, below or from the side. Grilling usually involves a significant amount of direct, radiant heat, and tends to be used for cooking meat and vegetables quickly. Food to be grilled is cooked on a grill, using a cast iron/frying pan, or a grill pan.
Outdoor cooking is the preparation of food in the outdoors. A significant body of techniques and specialized equipment exists for it, traditionally associated with nomad in cultures such as the Berbers of North Africa, the Arab Bedouins, the Plains Indians, pioneers in North America, and indigenous tribes in South America. These methods have been refined in modern times for use during recreational outdoor pursuits, by campers and backpackers.
An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.
Hāngī is a traditional New Zealand Māori method of cooking food using heated rocks buried in a pit oven, called an umu. It is still used for large groups on special occasions, as it allows large quantities of food to be cooked without the need for commercial cooking appliances.
The clambake or clam bake, also known as the New England clambake, is a traditional method of cooking seafood, such as lobster, mussels, crabs, scallops, soft-shell clams, and quahogs. The food is traditionally cooked by steaming the ingredients over layers of seaweed in a pit oven. The shellfish can be supplemented with vegetables, such as onions, carrots, and corn on the cob. Clambakes are usually held on festive occasions along the coast of New England, and at fundraisers and political events. Some restaurants and caterers offer clambake-style food.
Po‘e or poke is a Polynesian pudding usually eaten as a dessert.
The cuisine of Hawaii incorporates five distinct styles of food, reflecting the diverse food history of settlement and immigration in the Hawaiian Islands.[a]
Barbacoa or Asado en Barbacoa in Mexico, refers to the local indigenous variation of the primitive method of cooking in a pit or earth oven. It generally refers to slow-cooking meats or whole sheep, whole cows, whole beef heads, or whole goats in a hole dug in the ground, and covered with agave (maguey) leaves, although the interpretation is loose, and in the present day may refer to meat steamed until tender. This meat is known for its high fat content and strong flavor, often accompanied with onions and cilantro. Because this method of cooking was used throughout different regions by different ethnic groups or tribes in Mexico, each had their own name for it; for the Nahuatl it was called nakakoyonki; for the Mayan it was called píib; for the Otomi it was called thumngö.
Kālua is a traditional Hawaiian cooking method that utilizes an imu, a type of underground oven. The word "kālua" may also be used to describe the food cooked in this manner, such as kālua pig or kālua turkey, which are commonly served at lūʻau feasts. The word lūʻau is the Hawaiian name for the taro leaf, which, when young and small resembles cooked spinach after being steamed for a few hours. The traditional lūʻau was eaten on the floor over lauhala mats.
Barbecue varies by the type of meat, sauce, rub, or other flavorings used, the point in barbecuing at which they are added, the role smoke plays, the equipment and fuel used, cooking temperature, and cooking time.
A baking stone is a portable cooking surface used in baking. It may be made of ceramic, stone or, more recently, salt. Food is put on the stone, which is then placed in an oven, though sometimes the stone is heated first. Baking stones are used much like cookie sheets, but may absorb additional moisture for crispier food. A pizza stone is a baking stone designed for cooking pizza.
Tandoor bread refers to a bread baked in a clay oven called a tandoor.
A tandoor is a large vase-shaped oven, usually made of clay. Since antiquity, tandoors have been used to bake unleavened flatbreads, such as roti and naan, as well as to roast meat. The tandoor is predominantly used in Western Asian, Central Asian, South Asian, and Horn of African cuisines.
Pascuense cuisine, otherwise known as Easter Island cuisine or Rapa Nui cuisine incorporates the influences of the indigenous Rapa Nui people and Latin America. Notable ingredients include seafood such as fish, octopus (heke), eel, sea snails (pipi) and crustaceans (lobster), as well as sweet potato, taro, banana, pineapple, coconut, pumpkin, and poultry, pork and lamb meat.
Niue is an island in the Southern Pacific, mostly inhabited by Polynesians. The plantations are mostly filled with manioc, taro and breadfruit, but banana trees can be found. The wide range of exotic plants in Niue includes taros, pawpaw, coconuts, bananas, yams, cassavas and breadfruits: All are intensively used in the local cuisine.
The cuisines of Oceania include those found on Australia, New Zealand, and New Guinea, and also cuisines from many other islands or island groups throughout Oceania.
Lūʻau, Luʻau, Laulau, Lū, Rourou, Rukau, Fāfā, Hāhā, and Palusami are all related dishes found throughout Polynesia based on the use of taro leaves as a primary ingredient. While taro generally is known as a root vegetable for its starchy corms, the leaves are consumed as well. The base recipe is vegetarian. Most often, coconut milk was added, and later meat or seafood. The texture of the dish range from a thick soup to a dense cake.
Native Hawaiian cuisine refers to the traditional Hawaiian foods that predate contact with Europeans and immigration from East and Southeast Asia. The cuisine consisted of a mix of indigenous plants and animals as well as plants and animals introduced by Polynesian voyagers, who became the Native Hawaiians.
