What Caused A String Of Sushi Restaurant Fires?
Seven fires at sushi restaurants in the US were caused by spontaneously combusting tempura flakes, investigators have found.
A reaction between oxygen and oils used in tempura batter caused fires in five Wisconsin restaurants.
There were also fires in Minnesota, Virginia, and even Canada.
A fire investigator told ABC News: "The oil will combine with the oxygen in the air and in that chemical process, it releases heat."
The tempura flakes are also known as "crunch," or "tenkasu" in Japanese.
