answer:When I was a kid we used to pick wild blackberries in NY, and the kicthen at the resort we used to stay at would make pies with them. My neighbor in TN used to pick them sometimes also, and my MIL would make a syrup like topping for ice cream. The father of a friend of mine picked mushrooms on his property and we would eat them. When asked how he knows if a mushroom is poisonous or not, he answered, “I only pick the ones I know are safe. If I don’t know I don’t pick it.”
