It is first cured using large quantities of salt, either in a brine or in a dry packing; the result is fresh bacon (also known as green bacon).acon is cured through either a process of injecting with or soaking in brine or using plain salt (dry curing). In America, bacon is usually cured and smoked, and different flavours can be achieved by using various types of wood, or rarely corn cobs; peat is sometimes used in the United Kingdom.
