Choosing only non- toxic fern species will help keep the children in your house safe. But even with non- poisonous ferns , avoid letting children handle or ingest the plant.
Is it toxic? Eating raw or improperly cooked fiddleheads can cause symptoms of foodborne illness. The cause is likely an unidentified natural toxin in fiddleheads.
Symptoms usually begin 30 minutes to 12 hours after ingestion and may include nausea, vomiting, diarrhea, abdominal cramps, and headaches. The Best Way to Eat Fiddleheads First, steer clear of eating fiddleheads raw ; they should always be cooked first.
When eaten raw in large quantities, some varieties of fiddlehead ferns have been known to cause illness. There are thin, brown, paper-like scales covering the newly emerging fiddleheads. The fertile, spore-bearing frond is distinctive in shape, and also has a groove on the inside of the stem. There are two reasons for ferns to curl up , depending on the stage of the frond's growth cycle.
As it develops, it exposes more and more of the frond while protecting the still developing tissue. Once fronds are mature, the curling of the leaves indicates moisture loss and drying out of the foliage. Health risks A number of foodborne illness outbreaks also known as "food poisoning" from eating raw or undercooked fiddleheads have been reported in Canada and the United States since Other types of ferns , like foxglove and bracken ferns , are not safe to eat because they may be toxic or carcinogenic.
What Do They Taste Like? Fiddleheads have a grassy, springlike flavor with a hint of nuttiness. Many people agree that they taste like a cross between asparagus and young spinach. Some detect an artichoke flavor as well, and even a bit of mushroom.
Christmas fern Polystichum acrostichoides is a deciduous evergreen fern that grows in USDA plant hardiness zones This particular fern is known as a Christmas fern because some parts of the plant stay green all year long. Dark green leaves, or fronds, reach up to 3 feet long and 4 inches wide. Rinse the fiddleheads. Boil in water for about five to seven minutes or steam for ten to twelve minutes. Then saute lightly in butter. For a great book with 75 recipes for fiddleheads, check out this great little book :.
You can use fiddleheads like you use any vegetable. They work beautifully with egg dishes like omelettes and frittatas, go great with pasta dishes, soups and stir fries but also work alone as a side dish to accompany meats and fish. I had them the other night with lamb and mash potatoes. They are best to use soon after picking but they will last in your fridge for at least a week.
You can even have fiddleheads in the middle of winter as they can be frozen for up to a year. After years helping clients with digestive issues, Craig decided to pursue writing full-time.

Perhaps this is due to the influence of the early French settlers, many of whom were accustomed to eating fiddleheads in the old country.
They were also widely used by the Native Americans for centuries before the arrival of Europeans. Certainly, the fact that fiddleheads are one of the earliest fresh vegetables available in spring renders them decidedly appreciated after the long, cold winters of the region. They are produced by a number of fern species throughout much of North America. Wherever they may grow, they emerge in the first days of warm spring weather.
They are one of the first fresh vegetables available in the course of each year—a welcome treat and a wake-up call, premonitory of the comestible splendors to come.
They also serve as a gentle reminder of the constant change that typifies nature, as the ephemeral harvest season lasts but a few short weeks. Here in the Northeast, the predominant species for fiddlehead harvest is the Ostrich fern Matteuccia struthiopteris.
Many ferns make edible fiddleheads, but those of the Ostrich fern are unique, surrounded as they are by papery brown husks from which the developing frond emerges. They can be further identified by the smooth stem and deeply indented, U-shaped groove inside each stem.
Each tender, succulent coil is about an inch in diameter. The whole thing, including 2 or 3 inches of stem supporting the coil, is the part you pick and eat. Ferns tend to grow in moist, even wet conditions and often with less than full sunshine—Ostrich fern is no exception. Here in Maine, it is found growing along the banks of rivers and streams, around the margins of our thousands of ponds and lakes, in floodplains, and even in roadside ditches.
Since our sunshine is really never that intense, even at the peak of summer, they are occasionally found growing in open ground.
The plants reproduce by spores but often increase more rapidly via their aggressive rhizomes, sometimes creating stands of several acres in extent, often in the shelter of maples or ash trees.
