Walnuts, Basil and Salt all do not show up in my Discovery Tab at all. This is at 0 cooking with only the very beginning recipes known. So to all you people who keep saying that there’s nothing wrong, there definitely something bugged. And those are just the three I saw. Hopefully a patch will be forthcoming soon to fix this problem.
P.S.: Yes, I learned cooking on a fresh character JUST to test this very issue. Stop saying nothing is wrong.
