Pork rind

Pork rind is the culinary term for the skin of a pig. It can be used in many different ways. It can be rendered, fried in fat, baked, or roasted to produce a kind of pork cracklings (US) or scratchings (UK); these are served in small pieces as a snack or side dish and can also be used as an appetizer. The frying renders much of the fat, making it much smaller. Often a byproduct of the rendering of lard, it is also a way of making even the tough skin of a pig edible. In many ancient cultures, animal fats were the only way of obtaining oil for cooking and they were common in many people's diets until the Industrial Revolution made vegetable oils more common and more affordable. Microwaveable pork rinds are sold in bags that resemble microwaveable popcorn and can be eaten still warm. Pickled pork rinds, though, are often enjoyed refrigerated and cold. Unlike the crisp and fluffy texture of fried pork rinds, pickled pork rinds are very rich and buttery, much like foie gras. For the large-scale production of commercial pork rinds, frozen, dried pork skin pellets are used. They are first rehydrated in water with added flavoring, and then fried in pork fat at . Cooking makes the rinds expand five times their original size and float on the oil surface. The rinds are then removed from the fat, flavored, and air-dried. Antioxidants may be added to improve stability. Like many snack foods, pork rinds can be high in sodium and fat; however, they are low in carbohydrates and are sometimes considered an alternative snack food for those following a low-carbohydrate diet. According to Men's Health, a serving contains nine times the protein and less fat than is found in a serving of potato chips, which are much higher in carbohydrates. They add that 43% of pork rind's fat is unsaturated, and most of that is oleic acid, the same healthy fat found in olive oil. Another 13% of its fat content is stearic acid, a type of saturated fat that is considered harmless because it does not raise cholesterol levels.
