Smoked meat is a method of preparing red meat (and fish) which originates in prehistory. Its purpose is to preserve these protein-rich foods, which would otherwise spoil quickly, for long periods. There are two mechanisms for this preservation: dehydration and the antibacterial properties of absorbed smoke. In modern days, the enhanced flavor of smoked foods makes them a delicacy in many cultures.
