I'm surprised they didn't mention storing the avocado with a piece of onion. I just stored one for almost a week with no visible browning thanks to the onion. Just store the 2 cut pieces in a container and store in the fridge.
In fact I just tested this and I can give a simpler query to Google and get the correct result than ChatGPT.
If I search “onion avocado store” on Google it immediately pulls up articles explaining the chemical benefit of the storing method.
The same query on ChatGPT causes it to query me for more information about what I’m asking. Obviously it’s designed for conversational queries more so than Google which is another reason why simple queries like this are not superior on ChatGPT.
