I do this but I personally just pour a couple tablespoons into a glass of water then chug it down. You cannot heat the vinegar because it kills all the healthy bacteria in the vinegar so I wouldn't pour it into a soup or use it to marinate a steak .
Best way to mask the taste would be to mix it in with a protein shake.
Also Are you drinking Apple Cider Vinegar or another kind? That's the type you should be drinking specifically a brand called Braggs.
