The cider vinegar and honey mixture is an age-old concoction used as a medicinal base, called oxymel, as well as a refreshing drink when mixed with water.
I always use Bragg's Cider Vinegar and some cheap, locally-made honey sold in Tanduay bottles because the imported ones are so expensive. I found that there is actually a ready-made mixture from Wescobee being sold at some posh grocery stores, which I intend to try some day.
It's well-known for it's numerous benefits from curing arthritis to aiding weight loss. Personally I use it as a remedy for moderate cough and cold and sometimes as a ritual drink. I like the taste by itself but occasionally I have fun with it by mixing it with calamansi, fresh oregano, or mint. When using fresh herbs, I would steep the crushed herbs in a glass of hot water for a few minutes, then adding the honey-vinegar mixture in as a sweetener. My friend, the herbal witch Eric swears by putting some small garlic into the jar of the honey-vinegar mixture to give it flavor, and putting a teaspoon or two of the mixture in a glass of fruit juice.
Even with no colds, no coughs, or no arthritis, it's still nice to have a jar of this mixture around. It lasts long, and it can be a healthier alternative when you're craving for calories.
