I don't think cream of tartar will help much in whipped cream. But if you would rather something sweeter and thicker, cream of tar tar would be the thing to use (if making meringue). What I do to make whipped cream, is I use a pint of heavy whipping cream.
First I put it in the refrigerator for an hour or two, then when it is cool enough you Will need to mix it fast. Using a electric machine on high is best. Fell free to add sugar to your desired taste.
Once you think it is finished your whipped cream should be whipped just enough so that you are able to make sturdy peaks when you lift you utensil out of it. It should be light and fluffy to use. Hope this helps!wiki.answers.com»
