Well maybe failure is not the appropriate word. Maybe just meh is the right word. I love roasted vegetables especially if they get a little char on them so this sounded good. Alas, I was disappointed. So I'm posting this as a lesson learned - not everything blackened is good. I found this recipe here . They used green cabbage but I don't think that would make any difference. They were not kidding about opening your windows. I had a smoke filled kitchen even with the windows wide open. The smoke alarm even went off. Don't try this at home!
