Last Chance Foods: Grazing on Fiddlehead Ferns

Friday, April 27, 2012

The bright green spirals of ostrich fern fiddleheads are a beacon of spring. Delicate and grass-like in flavor, fiddleheads are one of the season’s most fleeting vegetables.

Registered dietitian Tamara Duker Freuman admitted that ferns kind of creep her out.

“It’s not the ferns themselves,” she clarified, ”it’s those little black spores underneath some of the fern leaves.” 

Nonetheless, Freuman (pictured below) got over her fear in order to enjoy fiddleheads, which she feels are a welcome spring addition after a long winter of kale and root vegetables.

“They’re very springy and fresh and grassy tasting,” she said. “They add a really nice dimension to a sauté of spring vegetables.”

While Freuman willingly advocated for fiddleheads, Tyler Gray, the co-founder of Mikuni Wild Harvest, had a confession.

“I mean, [fiddlehead ferns] look cool on the plate but they kind of taste like dirt,” he said with a chuckle. “That’s not something that, you know, the owner of a wild, foraged foods company should be saying. But, you know what? We all have our own opinions.”  

One way to ensure fiddlehead ferns are tasty, said Freuman, is to sauté them in butter and fresh thyme. Barring that, however, she noted that the ferns are worth eating because they are good sources of vitamin C and vitamin A.

“They’ve got a surprisingly high amount of protein,” she added. “You don’t think of vegetables as a good source of protein, but a very meager half-cup serving has four-and-a-half grams, whereas in a comparable green vegetable you’d expect to see less than one gram.”Tamara Duker Freuman

Fiddlehead ferns are also high in iron, Freuman pointed out.

“For vegetarians who aren’t getting iron from meat, to find a vegetable that’s high in iron is nothing to sneeze at,” she said.

When cooking up fiddleheads, though, Gray added one note of caution: there are two different kinds of edible fiddleheads — ostrich and bracken — and bracken ferns are slightly toxic.

Ostrich fiddleheads are the single green spirals most commonly seen in the Northeast and at grocery stores. Those are not toxic.

Bracken fiddleheads (pictured below) have multiple tendrils and are commonly described as looking like a curled eagle’s talon. Those are more prevalent along the West Coast.

“There’s a mild toxin in the bracken fern ... I know that you can’t eat too much of them,” Gray said.

The toxin does cook out, though, so it’s important when eating bracken fiddleheads to cook them thoroughly. 

Freuman, who has only ever seen non-toxic ostrich fiddleheads in grocery stores, shared her easy, no-measurements recipe for sautéed fiddleheads. That’s below.

Sauté of Fiddleheads, Snap Peas, Ramps & Shiitakes
by Tamara Duker Freuman 

  • Fiddleheads
  • Shiitakes 
  • 1-2 tsps butter
  • Fresh thyme
  • 1-2 tsp olive oil
  • Sugar snap peas
  • Ramps
  • Salt to taste

Blanch fiddleheads in a pot of boiling water until bright green and tender but still firm.  Set aside.

Sauté sliced shiitakes in 1-2 tsps of butter with fresh thyme and a sprinkle of salt until cooked.  

Set those aside and, in the same pan with 1-2 tsp olive oil, saute the sugar snap peas and ramps together until the snap peas are bright green and the ramps are soft and wilty.  

Add the blanched fiddleheads to the pan, season with salt to taste, and cook for 1-2 minutes more.  Remove from heat, mix in the mushrooms, and serve.

Don't be so sure that ostrich ferns are non-toxic. I ate them last weekend at a very nice restaurant that I've frequented dozens of times in the past 5 years. Thirty minutes after the meal, I was doubled over in pain, nauseous, and I actually passed out on the way home. I had diarrhea that night. I had never eaten fiddleheads before so was unsure of how they should taste. They were actually quite good -- except for the one piece that tasted bitter. Again, since I hadn't every had them before, I just kept eating. I just made it to my car after the meal when the severe stomach cramps hit. The whole episode was over in less than 12 hours, but I'd advise caution when eating fiddlehead ferns, even the ostrich ones.

Hi, Amy. If you want good factual information about fiddle heads, you should contact Robbin Moran at The New York Botanical Garden.
