 Every hour, first four hours, half and half, equal parts apple cider vinegar and water. I've tried it with orange juice. I've done it with soda. I've done it different ways. This is what I do. I absolutely am doing that. I do think it makes a difference. It has made a difference for me and the way my family likes it, which is, of course, it's a very personal thing, like the hot dog. Like, for example, ketchup. Perfect on a hot dog. No problem, fingers. Terrible.
