Explosive snack: a trip to a cafe ended for a Brazilian burns (4 photos + 1 video)
An absurd incident occurred at a fast food establishment in Curitiba, Brazil. A man decided to try a hot dish, but an unpleasant surprise awaited him. 
The footage shows a waitress handing a customer coxinha - traditional deep-fried chicken croquettes. When the man was about to try his delicacy, it suddenly exploded. 
Owner Christian de Souza Amaral stood with his mouth open as the stunned customer tried to wipe the scalding filling off his face.
He said: "The snack exploded with a loud sound, like a tire bursting. I was in shock watching the filling stick to his face. It was like a bomb went off." 
"We just cooked and put the koshinha on the counter, the customer was already in the hall. He said that the snack looked good and asked for one. The cook took it out of the fryer 5 minutes ago."
The workers provided first aid to the customer, but recommended that he go to the hospital. It was later discovered that the victim received burns. He was given medical assistance.
Biological science expert Laura Mariz explained: "There could have been air trapped between the dough and the filling, which expanded during frying, but not enough to burst the dough. But when the coxinha was bitten, it suddenly released that pressure, causing the explosion."
Coxinha, which means "thigh" in Portuguese, is a popular snack in Brazil consisting of shredded chicken and cheese wrapped in dough and deep-fried.
The dish originated in the state of São Paulo in the late 19th century and is now sold throughout the South American country.
