Invented in 1959 by Dr. DeForest C. Jarvis, Honegar is exactly what it sounds like: a mix of equal parts honey and apple-cider vinegar. Jarvis drew his inspiration from the drinking habits of rural Vermont farmers, who he believed to be particularly healthy. While the unpalatable recipe failed to catch on (though there are modern-day devotees), the science may not be all bad: both honey and apple-cider vinegar contain a slew of important antioxidants and are folk treatments for ailments like arthritis.
