The globe artichoke, due to the prevailing climate, is a vegetable rarely cultivated in Poland, but it is popular in Mediterranean countries, the Canary Islands, Egypt, and countries in Asia and South America. Interestingly, artichokes are considered the oldest vegetables cultivated by humans. However, it turns out that even they can surprise us.
Artichoke exploded while being cut. "There was soot mark on the knife"
The incident took place a few weeks ago. The woman who shared everything on social media emphasized that nothing serious had happened. However, she revealed that the situation unsettled her.
"I was cleaning the vegetable. I started from the leaves at the bottom to get to the upper part where the artichoke is lighter. When I cut it a second time, there was a spark, followed by the sound of an explosion and a trail of smoke. There was a soot mark on the knife. The smell was identical to what lingers in the air after lighting a firecracker," quoted the Italian portal Varese News, citing the woman's words.
This was not an isolated incident. In December 2013, in the Italian town of Olgiate Molgora, an artichoke also exploded while being cut, which a concerned woman reported to the police. According to local press, several similar incidents occurred across Italy on the same day, resulting in a few suffering burns. The police in Olginate and supermarket managers were notified, who immediately removed all artichokes displayed on their counters from the market. Similar incidents were also noted in 2003 and 2008 in Italy.
Why do artichokes explode?
Exploding artichokes do indeed occur. The reaction can be explained scientifically. Ammonium nitrate, one of the most commonly used fertilisers, can cause artichoke explosions. It's worth noting that ammonium nitrate is also an ingredient in many types of explosives.
Just a tiny amount of fertiliser getting inside the head, where it dries, can cause an explosion. One theory suggests that the reaction is triggered by sudden movement or heat, generated, for example, during the rapid slicing of the artichoke. Moreover, simply heating the vegetable can also cause an explosion. It's important to note that the reaction can be prevented by thoroughly washing the vegetable.
