Blah Blah Flowers

What's the longest time you've ever microwaved something? I don't mean giving it a minute, getting it out and stirring it, doing it for another minute and stirring it, doing it for another minute... I mean putting it on for an uninterupted period of time. I'm doing a cauliflower cheese meal which requires nine-and-a-half minutes of precious radiation and looking at the dial on my microwave I don't think I've had to go over ten minutes, but it goes all the way up to 60 minutes. What needs sixty minutes cooking? Could it actually work for sixty minutes straight without doing the explodey?
