What struck me in this piece is that the author tried to experiment but not to understand what he was trying to do. Chemically/Physically I mean.
I became a way better cook when I understood that the Maillard reaction happens starting at 140°C and caramelisation at 180°C (Wondered why this is the default setting of for oven cooking ? Now you know).[1]
The whole thing of cooking, apart from flavour mixing, is to bring your food (onions or anything else) to a high enough temperature to attain the desired reaction. And it is way complex than it seems with several parameters to play with : pan material for general heat conduction, stirring will allow homogeneous temperature conduction in the pan and will give time to the highest bits to cool down, fat helps for local heat conduction, adding water or wine will detach flavorous parts after "maillared" or caramelized (known as deglaced). And certainly many more that I still ignore.
So to come back to the point of caramelized onions, time can help but it is not the unique parameter. As suggested in other comments, you can slow-cook during the night and achieve easily a perfect result. You can also do it quite quickly (I have done it in 5 to 10 min I think) with a strong enough heat source and a lot of stirring to avoid pyrolysis.
In the end, it is no wonder that the famous post of Tim Urban is called "The cook and the chef [...]". [2] All of this makes me wanting to know more about "first principles" of cooking (mainly for flavour mixing, I still have a lot to learn on this point). Maybe receipe writers are making them up on the go, but most of the one I read have at least a bit of "chef" in them to be roughly good in their parameter estimates.
I am surprised no one else bring that up in HN. My main excuse to indulge in frequent visits of this site is that I think most people here try to be first principle thinkers when they comment. By the way, this is a way to long post for here, but I hope it will be useful for curious cooks.
