This ingenious hack keeps your avocado from turning brown

Nothing beats a delicious home-made batch of guacamole. 

The downside of the dip, is that it only lasts about 2 minutes in the refrigerator until it turns into a mushy brown vat of slime.

Lucky for you, we have found a clever and easy hack to save your guacamole from browning over.

The next time you make guac, just spray the top with some vegetable oil, coconut oil, or olive oil spray, then cover it in plastic wrap. It should stay green for up to 24 hours, according to PureWow.

This works because the spray creates an oxygen barrier around the mashed avocado, which eliminates any oxidation from occurring. This means that you could try this trick on sliced avocados too.
