An easy to remember trick to keep your cut avocados from turning that unappetizing brown.
If you have been following me for a while, you know that I collect little stories about this and that. I think that’s one of the skills that a home entertaining expert should have: being able to dole out a quick story for any moment or situation. It’s better than trying to crack the ice at a party with talk about the weather. Right?
Here are a few tidbits about avocados.
If you haven’t heard, the avocado is actually a fruit. Botanically, they belong to the same plant group as do laurels. So, basically, we eat what amounts to an enormous berry that has a single large seed.
Originally, avocados were thought to have come from Mexico. A while back, a friend of mine who is an anthropologist (yeah, I have one of those too), told me that there was some new evidence that suggests that avocados started off as several distinct varieties that came from Peru, the Guatemalan highlands, and along the Central American isthmus. They’ve even found the remains of an avocado plant that they think is 15,000 years old! It’s crazy that avocados have been around for that long.
Now for the practical part.
I love avocados. They’ve always been one of the staples in my home – ready to slice and eat at a moment’s notice. They’re a great “go-to” easy snack for friends who drop by and perfect for salads, sliced with veggies, or as guacamole (more on that later). Don’t forget the ever popular avocado toast that you find in almost every restaurant and that is so incredibly easy to duplicate at home!
The downside for avocados – they have an enzyme called polyphenol oxidase that causes our tasty fruit to start browning almost immediately after cutting. This is really inconvenient when you want to save half in the fridge for tomorrow’s snack. I mean, who wants to spread brown avocado on toast? Seriously.
Everyone has their own little trick to keep their avocados from turning brown. Twenty years in the restaurant business – I’ve heard them all, seen them all and tried them all!
One of the most popular tricks is my least favorite: drip lime or lemon juice on the cut parts, which is the same trick we use on cut apples. It works but, in my honest opinion, not very well. They still turn brown after about 4 hours and then the avocado has an extra flavor that you might not want.
Then there’s the one about keeping the pit attached. I don’t know why, but it seems to work for about 4 hours or so, and then the oxidization starts. The big downside is that the pit has to be attached to the uncut half. You can’t add the pit back to an avocado that’s been sliced.
The fact is, many of us will eat an avocado that’s been stored in the fridge and has browned a bit, but not for company consumption. So, a near miss just doesn’t cut it for me. If it’s going to work, it has to work really well.
The best method – tested in my own kitchen – place the cut half of an onion into an airtight container with your cut avocado. The onion releases sulfur dioxide which is a natural preservative – which puts a full stop on the browning. The great plus for this method is that it’ll keep cut avocados nice and fresh (cubed, sliced, peeled) for about 24 hours! And now you have a little onion to add to that toast.
See my video on this method. And enjoy your avocado!
