But why not cook the onions first, then remove them from the pan? Additionally, why have additional liquid in the pan when you would add the onions? I generally add mushrooms after cooking my onions and the liquid from the mushrooms is able to keep the onions from charring/burning.
In my experience, cooking the onion first is the always the right move. The only argument I could see against it is when frying peppers or carrots or potatoes or some other vegetables that may take longer to char or cook through. Even then, it’s not exactly wrong, just a higher risk of maybe charring the onions.
I really wish they would add steam cloud support to these games as well. I know that they have their Uplay cloud nonsense but it’s never worked on my steam deck
