was it 'crispy' on the outside? chances are, if you leave it in the jar overnight it's gonna 'sweat' a little and get a bit soggy. if it does, leave the jar open until it gets crispy again, close it, leave overnight and repeat until your stalks are snappy, even after it sweats overnight. once it's dry it should only take a couple days for the 'cure' to set it, and then it'll just keep getting better with age... (to a point).
