Apple cider vinegar has so many uses, including salad dressing and turning milk into buttermilk. Some people swear by cider vinegar as a digestive aid, a skin care product, and a hair conditioner. It costs next to nothing to make, and it doesn’t require any work. If you can make a spot for the jar on your counter, you can make this vinegar. This does need to sit for 6-7 weeks.
