Foraging might sound fun at first, but it isn't as easy as swinging by the local market. You have to put in the time, and you need to know which plants and fungi are edible, and which ones will cause illness or even death. Books on local wild foods and the foods of aboriginal peoples in your area are a good place to start, but it's important to spend time learning about the edible plants in the field, so to speak, side-by-side with a local foraging expert.
