Guacamole with tortilla chips is one of the easiest - and tastiest - snacks to whip up for a party.

However, the avocado dip inevitably turns into a mushy brown mess in just a couple of hours - meaning it's not the most appetising of leftovers.

Luckily, PureWow has discovered a nifty little hack to prevent your guacamole turning brown and keep it looking green and delicious for at least 24 hours.

All you need is one ingredient and you probably already have it in your kitchen cupboard:

Cooking spray.

The spray creates an oxygen barrier around the mashed avocado and stops any oxidation from occurring - which is what makes it turn brown.

Your guacamole should then stay fresh and green for around 24 hours.

It even works on halved avocados too. Phew.
