Is it true that the freezing method will only last for 6 months at the most and then what?
This second method you offer in glass jars is great. In fact I don't know if you know this type of preparation, but pickled aubergines and chicken or various products are preserved very well, because of the vinegar contained in the preparation. The same goes for canned tomatoes or peppers, always in glass jars and vacuum packed!
