Made this using the crockpot method, and it turned out very good.
Next time however:
It definitely needs extra salt, plus it might be worthwhile doing the precook on the onions with the reduced apple cider first. I'd also like to try it with hard cider instead of wine.
Absolutely doesn't need all four onions, I can definitely half those, and while I used a mushroom medley, this is a rare time I think the normal crimini/baby bella would be better.
