Just use water to know the taste, I think this is important should you get a bad batch...then you can describe the taste if necessary.
Later you can add juice and I don't think it matters how much, so long as no added vit c.
I like to take my Miracle-Mineral-Supplement on an empty stomach and I keep it an hour apart from food, but Fireguy and even Humble don't believe food is a problem.
Please keep us posted, I look forward to hearing about your progress!
