Producing America's number one Halloween treat for more than half a century, these sweet sisters oversee the production of 30,000 Smarties tablets per minute at their family-run candy factory in Union, New Jersey. For a company that spends no money on advertising, Jiffy Corn Muffin Mix has cornered the market and makes enough mix to produce 1.5 billion muffins per year. It takes mechanical shakers, a river of fruit, and high-tech camera equipment to produce 10 million tart dried cherries every year.
