help. i've been buying nonfat store-brand vanilla yogurt and draining the excess water out of it thru cheesecloth. has been working well. today i bought nonfat dannon vanilla yogurt and tried to do the same and the yogurt was so runny, all the yogurt just drained thru the cheesecloth.
i tried it twice, doubling the layers of cheesecloth the second time. still no luck.
any suggestions? and why would one brand of nonfat yogurt be some much more firm/runny than another?
