Pressure cooking is the process of cooking food, using water or other cooking liquid, in a sealed vessel known as a pressure cooker. This simulates the effects of long braising within a shorter time.
Mortar and pestle are implements used since ancient times to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, medicine and pharmacy. The mortar is a bowl, typically made of hard wood, metal, ceramic, or hard stone, such as granite. The pestle is a heavy and blunt club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar, where the pestle is pressed and rotated onto it until the desired texture is achieved.
Chopsticks are shaped pairs of equal-length sticks that have been used as kitchen and eating utensils in virtually all of East Asia for over two millennia. First invented and used by the Chinese during the Zhou Dynasty, chopsticks later spread to other countries across East, South, and Southeast Asia including Japan, Korea, Cambodia, Laos, Nepal, Malaysia, Myanmar, Singapore, Thailand and Vietnam. Chopsticks are smoothed and frequently tapered and are commonly made of bamboo, plastic, wood, or stainless steel. They are less commonly made from titanium, gold, silver, porcelain, jade, or ivory. Chopsticks are held in the dominant hand, between the thumb and fingers, and used to pick up pieces of food.
A knife is a tool with a cutting edge or blade attached to a handle. Mankind's first tool, knives were used at least two-and-a-half million years ago, as evidenced by the Oldowan tools. Originally made of rock, bone, flint, and obsidian, over the centuries, in step with improvements in metallurgy or manufacture, knife blades have been made from bronze, copper, iron, steel, ceramics, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin.
A drink can is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic drinks, fruit juices, teas, herbal teas, energy drinks, etc. Drink cans are made of aluminium or tin-plated steel. Worldwide production for all drink cans is approximately 370 billion cans per year worldwide.
A Dutch oven is a thick-walled cooking pot with a tight-fitting lid. Dutch ovens are usually made of seasoned cast iron; however, some Dutch ovens are instead made of cast aluminium, or are ceramic. Some metal varieties are enameled rather than being seasoned. Dutch ovens have been used as cooking vessels for hundreds of years. They are called casserole dishes in English-speaking countries other than the United States, and cocottes in French. They are similar to both the Japanese tetsunabe and the sač, a traditional Balkan cast-iron oven, and are related to the South African potjiekos, the Australian Bedourie oven and Spanish cazuela.
A sieve, or sifter, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal. The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate solids from liquid.
A spatula is "a broad, flat, flexible blade used to mix, spread and lift material" including foods, drugs, plaster and paints. It derives from the Latin word for a flat piece of wood or splint, and hence can also refer to a tongue depressor. The words spade and spathe are similarly derived. The word spatula is known to have been used in English since 1525.
Aluminium foil, often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm ; thinner gauges down to 6 micrometres are also commonly used. In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm thick, and heavy duty household foil is typically 0.024 mm. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplanted tin foil in the mid 20th century.
Cast-iron cookware is valued for its heat retention properties and can be produced and formed with a relatively low level of technology. Seasoning is used to protect bare cast iron from rust and to create a non-stick surface. Types of bare cast-iron cookware include panini presses, waffle irons, crepe makers, dutch ovens, frying pans, deep fryers, tetsubin, woks, potjies, karahi, flattop grills and griddles.
A kitchen utensil is a small hand held tool used for food preparation. Common kitchen tasks include cutting food items to size, heating food on an open fire or on a stove, baking, grinding, mixing, blending, and measuring; different utensils are made for each task. A general purpose utensil such as a chef's knife may be used for a variety of foods; other kitchen utensils are highly specialized and may be used only in connection with preparation of a particular type of food, such as an egg separator or an apple corer. Some specialized utensils are used when an operation is to be repeated many times, or when the cook has limited dexterity or mobility. The number of utensils in a household kitchen varies with time and the style of cooking.
