Trick to keep your avocados fresh

Picking the perfect avocado is a skill learned from years of experience.

It's the accumulation of hours and hours of standing in the supermarket prodding the green fruit to find one with the perfect amount of squishiness - not too much, not too little.

But even as avocado experts it can be frustrating to find those we picked so lovingly can go off before we have a chance to enjoy them.

One shopper who was fed up of enduring the heartbreaking experience has found a genius solution to stop them going brown for up to a week.

Looking for a 'greener' way to store avocados that didn't involve using a plastic container, the mum stumbled across a very natural solution using something you probably already have in your fridge.

After slicing an avocado and enjoying one half, she wraps the other half in a lettuce leaf to keep it ripe and delicious.

She shared a photo of her avocado online looking the perfect shade of green, claiming it had been sliced open a week ago, to prove just how efficient the method was.

"I sort of accidentally discovered that I have been throwing away first class food wraps," she wrote on Facebook.

"Lettuce leaves, primarily the outer ones that are a bit harder, make for excellent food wrap. They're designed for that purpose in the first place.

"It was all good for today's breakfast. Incidentally, lettuce leaves even keep bread buns fresh."
