A Kiwi woman's easy trick for keeping avocado fresh in the fridge after it's been cut open is proving a hit online.
Cherry Gaddes, whose Facebook page says she's based in Piako, Waikato, has racked up 11,000 reactions on her post which has been covered by the UK's Metro and Australia's news.com.au.
Her food hack is simple: wrapping an outer lettuce leaf around cut avocado and keeping it in the fridge.
Apparently, this makes the beloved and often expensive vegetable stay green longer, delaying its browning process.
"Sort of accidentally I discovered that I have been throwing away first-class food wrap," says Gaddes.
"Lettuce leaves, primarily the outer ones that are a bit harder, make excellent food wrap! Since they're designed for that purpose in the first place... who knew?"
She posted the food advice with an image of a fresh, green looking half avocado she says she'd used the hack on.
"This avo was cut a week ago, and stored in the fridge ever since, wrapped in lettuce leaf. All good for today's breakfast. Incidentally, lettuce leaves even keep buns fresh!"
Gaddes adds that the hack is a form of "recycling" and "keeping it green".
Indeed, using parts of a lettuce that you're going to throw away anyway is far more sustainable than using plastic wrap or cling film.
