Is open kettle canning still a recommend food processing practice?
Open-kettle canning means putting hot food into hot jars and putting a prepared lid on it with no further processing and this is no longer a recommended practice. It previously was used for sealing pickled products and jams and jellies. The correct procedure for these products today is to process in a boiling water bath (jams and jellies) or in a simmering water bath (pickled products).
