Sounds evil. Though I did laugh at this (my bad):
In January 2013, the Bratli Tunnel at Tysfjord was damaged when a lorry load of caramelised brunost caught fire. The high concentration of fat and sugar in the cheese causes it to burn fiercely at sufficiently high temperatures, and the fire was still burning five days later.
My fridge is particularly pungent at the moment due to a rather nice ripe stilton.
