I never realized how widespread this was until I brought dishes to group meals (as in Slow Food) and people complimented me for my caramelized onions.
Most people don't want that though most of the time. In 99.9% of applications fully caramelized onions simply aren't nearly as pleasant as onions that have been cooked until soft and very slightly caramelized.
(Making actual caramel, OTOH, that's far easier on gas or induction.)
Let me tell you a story. If you go off road just about anywhere in Mexico that's dry enough and interesting enough, and it's possible to go slow enough to have enough clearance, you will find cheap 2WD rear drive cars that are already there. I have seen some amazing accomplishments from these vehicles that almost no US driver would dream of taking off road. Still, I wouldn't trade my 23 yo lifted 4wd truck for them at all. Over time, I'm going to come out ahead, there's simple no dispute.
I don't doubt that you could caramelize onions on the shittiest stoves possible, probably you could do it, with enough patience and care, with a magnifying glass on a hot summer day. But the OP was emphasizing that it's really no big deal, you don't even have to pay attention. I at least have great equipment, but I've stayed in dozens of AirBnBs that didn't have great equipment, same with friends and family. Got to pay attention then.
The idea that there is no difference is completely ridiculous.
If you happen to already have a big 4WD truck which you need for other things then obviously it makes sense to use that anywhere it might give you an advantage. Sometimes that advantage turns out to be pretty marginal in practical terms but for you, because you're used to to handling the terrain with ease, switching to a crappy 2WD car would feel like a massive downgrade.
Another kitchen analogy, some people spend their whole lives chopping things with a blunt knife. When I offer to help out and realise this state of affairs my first reaction is "how the hell can anyone chop tomatoes with this?!" ... but of course they can, it's just slower and more annoying.
If you read Julia Child she is emphatic that onions should almost never be browned.
Guess what? I brown onions in my French recipes (rustic, eh?), and I char my peppers. I would submit that la comida de la gente is likely more plebian than fucking elitist French cuisine, no?
Pan quality is still going to matter.
But you don't need $50k in kitchen gadgets to properly caramelize onions...
Either you have an electric stove - not an induction stove, or you have a VERY bad pan (for an induction stove).
No idea if that’s better for cooking than concentric rings, but it looks really cool.
If you want to know how I found this out: I wasn't using my brain and touched the element after spilling something on it. I received a fairly bad burn as a result. I am saying this because saying "the element doesn't get hot" can put the wrong idea in someone's head.
