pickling onions questions

[Maheel]

Been looking at some old threads as i want to do some PO's


From my reading it does not need to be done "hot" to make a vacuum / pasturise in the jar?

Is that right ?

Is there any reason i cannot do these in a sealed plastic container if i wanted to do some bigger batches?

thanks

When you say hot do you mean immersed in boiling water for tightening the lids?
The hot vinegar will make a vacuum, when I make pickled beetroot I heat up the water and vinegar fill to the top and fit the lid, then count the pops as the lids pull in for the number of jars.
I would think it could be done in plastic, after all the wort can be kept in plastic.

As long as your containers are clean and sterile you should be right, pickled onions are pretty bulletproof in my experience as they should be sitting in vinegar anyway. I do heat my vinegar, don’t normally boil but get it close when adding spices etc.
