Hi, I was thinkin' that the green edge is not enough, because some dishes have different names in the quest window, for translations mistake.
Ex: Cook and serve "Spaghetti al pomodoro"
Book: "Spaghetti al sugo"
The problem is that some players, mostly newbies doesn't recognize the dish to cook and they tell "Why I can't terminate this quest?".
So my suggestion is to add some symbol to "Show me" modality, like green edge plus "*" or something like that in the corner of the dish window.
