Lard is pig
Domestic pig
The domestic pig is a domesticated animal that traces its ancestry to the wild boar, and is considered a subspecies of the wild boar or a distinct species in its own right. It is likely the wild boar was domesticated as early as 13,000 BC in the Tigris River basin...

Fats consist of a wide group of compounds that are generally soluble in organic solvents and generally insoluble in water.

 in both its rendered and unrendered forms. Lard was commonly used in many cuisines as a cooking fat or shortening
Shortening
Shortening is any fat that is solid at room temperature and used to make crumbly pastry. The reason it is called shortening is because it prevents cross-linkage between gluten molecules. Cross linking is what causes doughs to be sticky. Seeing as cake is not meant to be sticky, shortening is used...

 content and its often negative image; however, many contemporary cooks and bakers favor it over other fats for select uses. The culinary qualities of lard vary somewhat depending on the part of the pig from which the fat was taken and how the lard was processed.

Lard production

Lard can be obtained from any part of the pig as long as there is a high concentration of fatty tissue
Adipose tissue
In histology, adipose tissue or body fat or fat depot or just fat is loose connective tissue composed of adipocytes. It is technically composed of roughly only 80% fat; fat in its solitary state exists in the liver and muscles. Adipose tissue is derived from lipoblasts...

The loins are the sides between the lower ribs and pelvis, and the lower part of the back. It is often used when describing the anatomy of humans and quadrupeds . The anatomical reference also carries over into the description of cuts of meat from some such animals, eg...

. Leaf lard has little pork flavor, making it ideal for use in baked goods, where it is valued for its ability to produce flaky, moist pie crusts. The next highest grade of lard is obtained from fatback

, the hard subcutaneous fat between the back skin and muscle of the pig. The lowest grade (for purposes of rendering into lard) is obtained from the soft caul fat
Caul fat
Caul fat is the thin membrane which surrounds the stomach internal organs of some animals, such as hogs, cows, sheep, and pigs, also known as the greater omentum. It is often used as a natural sausage casing and to encase fegatelli , faggots , or pâté . Caul fat is also known as Lace...

Lard may be rendered by either of two processes: wet or dry. In wet rendering, pig fat is boiled in water or steamed at a high temperature and the lard, which is insoluble in water, is skimmed off of the surface of the mixture, or it is separated in an industrial centrifuge
Centrifuge
A centrifuge is a piece of equipment, generally driven by an electric motor , that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis...

. In dry rendering, the fat is exposed to high heat in a pan or oven without the presence of water (a process similar to frying bacon). The two processes yield somewhat differing products. Wet-rendered lard has a more neutral flavor, a lighter color, and a high smoke point
Smoke point
The smoke point generally refers to the temperature at which a cooking fat or oil begins to break down to glycerol and free fatty acids, and produce bluish smoke. The glycerol is then further broken down to acrolein which is a component of the smoke. It is the presence of the acrolein that causes...

. Dry-rendered lard is somewhat more browned in color and flavor and has relatively lower smoke point.

Industrially-produced lard, including much of the lard sold in supermarkets, is rendered from a mixture of high and low quality fat sources from throughout the pig. To improve stability at room temperature, lard is often hydrogenated. Hydrogenated lard sold to consumers typically contains fewer than 0.5g of transfats per 13g serving. Lard is also often treated with bleaching and deodorizing agents, emulsifiers, and antioxidants, such as BHT
Butylated hydroxytoluene
Butylated hydroxytoluene , also known as butylhydroxytoluene, is a lipophilic organic compound that is primarily used as an antioxidant food additive as well as an antioxidant additive in cosmetics, pharmaceuticals, jet fuels, rubber, petroleum products, electrical transformer oil, and embalming...

. These treatments make lard more consistent and prevent spoilage. (Untreated lard must be refrigerated or frozen to prevent rancidity.)

Chemistry of lard

Lard is mainly fats, which, in the language of chemistry are known as triglyceride
Triglyceride
A triglyceride is an ester derived from glycerol and three fatty acids. There are many triglycerides, depending on the oil source, some are highly unsaturated, some less so....

s. These triglycerides are composed of three fatty acids and the distribution of fatty acids varies from oil to oil. In general, lard is similar to tallow in its composition. Pigs that have been fed different diets will have lard with a significantly different fatty acid
Fatty acid
In chemistry, especially biochemistry, a fatty acid is a carboxylic acid with a long unbranched aliphatic tail , which is either saturated or unsaturated. Most naturally occurring fatty acids have a chain of an even number of carbon atoms, from 4 to 28. Fatty acids are usually derived from...

However, in the 1990s and early 2000s, the unique culinary properties of lard became widely recognized by chefs and bakers, leading to a partial rehabilitation of this fat among "foodies".

 or schmalz. Dripping (or "schmalz") sandwiches are still popular in several European countries - in Hungary they're known as "Zsíroskenyér" or "Zsírosdeszka", and in Germany pork fat is seasoned to make "Fettbemme". Similar snacks are sometimes served with beer in Poland, Czech Republic and Slovakia. They are generally topped with onions, served with salt and paprika, and eaten as a side-dish with beer. All of these are commonly translated on menus as "lard" sandwiches, perhaps due to the lack of familiarity of most contemporary English native speakers with dripping. Attempts to use Hungarian "Zsir" or Polish "Smalec" in British recipes calling for lard will soon reveal the difference between the wet-rendered lard and dripping. In Taiwan
