I am looking for olives that I can use when making pasta. Not sure where to find them. I also want to avoid vinegar. So far all that I have been able to find are canned olives (which are in salt water), but I recently read an article discussing BPA in canned foods so I'm looking for an alternative. The ones in the salad/refrigerated section all seem to have vinegar as a preservative. Is there such a thing as fresh olives?
