Only needing around 10 minutes in the oven, according to DaveHax, the avocado should come out soft enough to eat.

Before tucking in, however, the avocado wrapped in foil should be left to cool completely on a cooling rack.

"You may need to leave it in the oven for longer, depending on how hard it was to begin with," he added.

"When it's cool, remove the foil and carefully cut it in half; remove the stone, and you should it's now soft, ripe and perfect for eating."

Some viewers disputed that the avocado looked rather ripe before DaveHax put the avocado in the oven.

Others tried the hack themselves and proclaimed: "It worked." One commentator said: "I tried this and it worked.

"I put it in the oven two times, for 10 minutes, at 200 degrees. So it was a total of 20 minutes for me.

"I put in three avocados at once, on a baking sheet. After the 20 minutes, I left them in there to soften, when the oven was off. So surprised it actually worked.

"While the oven was off, if there was a hard side, I just took turns rotating it on its hard side until all sides were soft. Thank you for this hack! I was able to make guacamole the same day."

For some, however, the hack "didn't work" and people complained it was a waste of time. Another posted: "All this does is cook it. It's not ripe. This tastes horrible."

To ensure a tasty ripe avocado, some planning might be involved, but BBC Good Food recommends placing the avocado in a paper bag with a banana.

Due to the release of ethylene gas, the avocado should be fully ripened within three days.
