How might one test their Instant Yeast?
I'm wondering if the jar of Instant Yeast I have has perhaps lost it's ooomph and wondered if there was a quick and simple test I can put it through? Unlike Active Dry Yeast that would foam and bubble profusely when added to a cup of lukewarm water, Instant just clouds up the glass but creates no foam. (This is precisely why I'm wondering if mine is dead, if it SHOULD have foamed and bubbled.)
