Lebanon has had very uneven population growth over the past 50 years, and it's currently growing at 1% per year. Its urbanization rate is rapidly growing and expected to reach 86% in 2020, at which point its urban population will reach 4.1 million, with a total population pushing 6 million in the next decade.
Fresh fiddleheads should be stored with care to keep them fresh and intact. Loosely wrap unwashed fiddleheads in a paper towel and store in a plastic bag in the refrigerator. While fiddleheads can stay in the refrigerator for up to 10 days, it's best to eat them within a few days for maximum freshness and quality. You can also blanch and freeze fresh fiddleheads if you want to enjoy them later in the season. Frozen fiddleheads keep for up to one year.
Always blanch, boil, or steam before eating. Fiddleheads should be eaten soon after purchase, although they may be stored for a few days, tightly wrapped, in the refrigerator, if need be. They can also be stored in water in the fridge for up to a week if you change the water every two days. Most of the greens sold as fiddleheads are immature ostrich ferns (Matteuccia struthiopteris) of northeastern North America, which are safe for most people to eat.
