In the last couple of weeks I've tried my hands on pickling and in general the results have not been bad at all! I now want to try to pickle onions. I managed to get my hands on some smallish onions, and I'm all set to go. I looked at recipes at the internet and most of them tell me to brine the onions for 24 hours first. Is this really necessary and why is this done? And please let me know your favourite pickled onion recipes as well !
