It appears that there's no tag for foraging or food (fruit/veg/fungi) from the wild. Likely questions would appear to be on topic, analagous to [ingredient-selection] for bought ingredients.
While it's on-topic (and in use) at outdoors.se, many culinary aspects would probably find a better audience here.
So I think we should have a tag and accept questions. I have a question in mind to start things off unless someone can point out a good or policy reason why we shouldn't.
