If you love avocados as I do, you likely want to enjoy them regularly. But here’s the problem: if you stick to portions such as a quarter of an avocado, you want to be able to store them without their turning into brown fruits (which aren’t so appetizing).
You’ve likely tried all kinds of ways- rubbing them with lemon or wrapping them very carefully with plastic wrap. But they still get all brown on the part that’s been cut.
Well, here’s a bit of magic: put some diced onion in a bowl or a container and then store your cut avocado skin side down and cover. Then store it in the fridge. No more brown edges. You can cut a quarter off the next day and so on without putting in newly cut onions.
This is a photo of mine after a day after it was first cut. This one was a little overripe but still very yummy.
Enjoy!

Great information, Thanks!
Does the avocado taste like raw onions?
Not at all, Carolyn! The avocados are placed skin side down and the flesh does not come into contact with the onion itself. I love this as I can eat an avocado myself over three or four days and it is still great looking and tasting!
How does this work, and how is it better than covering the cut surfaces to prevent oxidation?
Great question! Onions emit a sulfur gas which acts as an antioxidant. While covering the cut surface is one way to prevent oxidation, it doesn’t work nearly as well as the onion. Try it!
