Spontaneous combustion of tempura flakes blamed for sushi restaurant fires
A popular sushi ingredient is believed to be the cause of seven restaurant fires across the country, after officials discovered the product could self-heat and spontaneously combust.
The fires, five of which happened in Wisconsin, were the “result of a preparation technique” used to make deep-fried tempura flakes, commonly referred to as “crunch” but properly called tenkasu or agedama, according to a statement from the city of Madison’s fire department.
