Both pork and products made from pork come from the hog and can be found almost anywhere in the world. The popularity of pork as a food source is partly due to the vast number and variety of ways it can be prepared and the number of derivative products that are made from it. Humans began domesticating pigs around 5000 BC, and have thus had plenty of time to discover and perfect many delicious ways of preparing pork. It is widely available for sale in most countries, and you can even buy pork online (hint, hint). Some of the more popular pork products include ham, pork tenderloin, baby back ribs, bacon, hot dogs, ham hocks, and sausages.
