Anyone know where SF is?

As I was caramelizing onions for my baked beans, I recall seeing a pic that
someone posted of his caramelized onions. She told him that they were not
caramelized but just browned. I think she based this on the cooking time
which was I think less than an hour.

Anyway... Was wondering what the difference was? My caramelized onions sure
do look brown.
