The Secret to Keeping an Avocado Green

I think most people would agree that avocados are great – they’re creamy, delicious, great on sandwiches, in guacamole and full of healthy fats. The one thing that no one likes about them, however, is that they quickly turn an icky brown color after you cut them open. I’m a visual person and I like my food to look good so this really doesn’t make me happy.

I’ve tried lemon juice, leaving the pit in, and covering them with plastic wrap but I still end up with at least some spots of brown. Recently I read a blurb in a magazine about submerging a cut avocado in water to keep it from turning brown. I promptly forgot about it, but the next time I had an avocado half leftover it suddenly popped into my head.

Could that possibly work? I put 2 avocado halves in a bowl of water, placed it in the fridge and came back 8 hours later. Do you know what I found? The avocado at the top of this post! I pulled it out of the fridge (looking perfectly green as if I just cut into it) and took a picture of it. Then I put it back in the fridge and 36 hours later it just barely had a tinge of brown.

The only issue with this method is the avocado becomes wet. If you leave the peel on, only the exposed part is wet and that doesn’t really matter for guacamole, other dips, smoothies, etc. For sandwiches or other recipes where you’d want a dry avocado, I think you could just wipe it off with a paper towel and it would probably be fine.

Do you have any special tricks for keeping an avocado green?

    Thank you. I’ve thrown away so many because of the icky brown color. This helps big time.

      @Erin – Leanna above said the same thing – we must read the same magazines. Give it a try next time you have an avocado!

    I heard that recently too! I normally just eat the whole damn avocado though. SO good.

      @Leanna – we must have read the same magazine (was it Bon Appetit?). I know what you mean about eating the whole thing though – avocados are dangerous like that!

    I think avocados are small for a reason, you can eat one in one sitting. We were having this discussion last night, my daughter’s fiance makes a wonderful guacamole and it just doesn’t keep well because he uses so many avocados so we have to eat it all at one sitting.

      @Medifast Coupon – that’s true, you can sometimes eat avocados in one sitting. I get really big ones sometimes (maybe because I’m in California) and I can only manage 1/2 of those at a time. Having too much guacamole is a fun problem to have! 😉

    If you leave the pit in the half you are not using it will keep it fresh. You can also drop the pit into the bowl of guac and it will help keep it fresh too.

    I purchased a pint of guacamole and it stayed fresh and green in the fridge for close to a week. There must be an ingredient that when added, it keep it fresh longer. So what is it?

      @Chuck – citric acid can also help keep them green

    […] actually, even for the guacamole you can also use the bowl and water trick… whaaat?!!! Yes, you just need to place the pit into the bowl with water and as long as the pit remains under water the guacamole remains green and doesn’t turn brown.

    Just try it and share your observations.

      Jess, I used cold water from the tap and then put it in the fridge, so it ended up ice cold.

    I wasn’t thrilled with the idea of an avocado with a watered flavor and then it dawned on me. I can’t use lemon juice (I’m allergic to fruit), but I can drink white wine. So, I filled the bottom of a seal-tight plastic bag, put a cut avocado, pit attached, “face” down and sealed the baggie. Tonight, two days later, I took the baggie from the refrigerator, opened it, and removed the just-like-new avocado! The taste of wine was barely evident. EUREKA!
