Grey pickled onions.

[mazer]

How can I keep my pickled onions white? I use distilled vinegar, as suggested for colour preservation, but they still turn greyish after a few weeks.

Hmmm... send your recipe, if you don't mind. Also, where are you storing your jars?

Have you religiously sterilised your jars? Are they hot when you put your product in? Having said that, it's fairly normal that they don't stay pristine white, the ones we buy in England (and we created them) are preserved in brown vinegar, so that solves the discolouration problem!!! They are already discoloured from the beginning.

White bought ones have nasty preservatives to keep them white.
