There are strict rules about foraging anything in state parks and city parks. The laws aren’t clear at all, so it’s always best to ask someone more experienced. Whenever we go picking mushrooms, we bring a towel/picnic blanket to drape over the basket just in case.
Puffballs of all sizes grow in the forest, alongside roads, in the middle of a green grassy lawn, they can really grow anywhere! You can stir fry them, cook them in the oven and my absolute favorite, is pretending they are pancakes!
I find these mushrooms the most rewarding to pick, because even a small one is enough as a side dish to any meal and the bigger ones can feed an entire family! Every time I’ve looked for hens, I found at least one and usually had 2-4 kilos (4-9 pounds) in just 30 minutes of searching. Of course, you can also find a single mushroom that weighs 13+ kilos (30+ pounds).
