It is a very interesting topic beyond food. When I first came to America, I was surprised and confused by the lack of diversity on vegetables in grocery stores. Around the small Midwest town I lived, there were many weeds that look edible. I had never heard any local Americans eat them, though. I thought it was simply because there were a surplus of food in America. Many many years passed. In our backyard, there are many weeds that look edible. I have tried only two, dandelion and a kind of fern. I hesitate on the others, although some looks similar to what I had eaten before. I am concerned they might cause health issues, from minor stomach discomfort to serious food poisoning. It is not like I had no experience in forage. I regularly foraged for weeds, ferns, mushrooms when I was a child. I love them better than carrots, celeries, cabbages, etc. They simply tasted better. But I hesitate at the weeds and mushrooms in my backyard. Whenever I see some new vegetables in the fantastic Berkeley Bowl, I will get some, google recipes, and try them. Whenever I see these weeds in restaurant menu, I will order to have a try. First, because I love trying new things. Second, I believe it is sustainable, both from where I grow up and from my education. But I still hesitate at the weeds and mushrooms in my backyard. One can explain it from the point of view of evolution. Somehow, I feel it is more than that.
