Ok so I have a question. I use my whipper a lot for whipped cream (My fiance loves it). But, I want to make a smoother whipped cream. Typically I whisk together a pint of heavy cream, a few tablespoons of powder sugar and a splash or two of vanilla. I charge it with 1 cream charge, shake and go. But, it is very...stiff...for lack of better terms. Whenever I go to Starbucks and they use their whippers they get a really smooth texture. What can I do to make a better, smoother cream? Thanks!
