The internet has gone into a frenzy after a video showcasing a so-called 'cooking-hack' for frying eggs went viral. The video, posted by a TikTok user from Germany, shows water from a cucumber being used instead of oil.

The woman claims she learned the trick from an "Italian grandmother", saying she will "never do it with oil again". The video shows her rubbing a chopped cucumber across a pan, before cracking and frying an egg. The egg appears a success, with what looks like a runny yolk and leaving behind little mess in the pan — however, not everyone in the comments was impressed.

Olive oil is incredibly popular in Italy, with one person writing in the comments: "An Italian grandmother would NEVER replace oil with ANYTHING."

A second user said: "As an Italian, absolutely not. No Italian grandma would replace oil."

"My nonna would slap my a** if I don’t use the olive oil from our garden," another said.

Others argued olive oil is important as part of a balanced diet, although the person behind the video never said the unusual technique is for health reasons.

One user person wrote: "What's wrong with a lil bit of olive oil? It's actually healthy."

"There is nothing wrong with baking in some oil, people need to stop making nutritious foods look bad," another said.

"Oil is healthy. I don't get why people are so scared of it," another comment read, to which the creator replied saying: "I love oil. But its a fun hack. Don't worry."

Others pointed out she could've just used water instead of a cucumber, while some suggested it only worked because she used a non-stick pan.

Some claimed to have even tried out the "hack".

"It didn't work for me," said one user, to which somebody replied: "Same!"

However, at least two other users claimed it worked for them.

The video has been viewed more than 17 million times on TikTok and has received thousands of comments.
