Chopped onions in metal or plastic containers Which preserves diced onions better? A plastic or metal container?? I'm trying to figure out which is a better storage container.
The key thing to look for is that the container closes as tight as possible. Metal or plastic doesn't matter. However, I would probably use metal or glass, since plastic can absorb some of the flavour of the raw onions. This would then make that container unsuitable for storing other things.
