Tofu fans, beware.
From Monday's edition of The Oregonian:
Just after 8:15 p.m. fire crews were called to an apartment building in the 300 block of Northwest Fifth Avenue in the heart of Old Town.
"When they arrived they found a woman sitting outside crying," Corah said. "She said there'd been an explosion and she was upset. She had a slight burn on her left hand, but was otherwise not hurt."
The woman told investigators was cooking tofu and had rinsed out the pan with water when there was explosion. The blast was so powerful that it blew a 4 by 6 window out of the building and onto the street, Corah said.[Source]
