Fiddleheads are typically par-boiled to tenderize them and to remove some of the bitterness of the raw shoots. One of the most popular ways to prepare fiddleheads after par-boiling is to sauté them, often with garlic, onions, and lemon. I find fiddleheads cooked this way are excellent tossed with pasta. So I created a simple dish with wild nameko mushrooms and fiddleheads... a kind of "forager's pasta." This dish is intensely satisfying, even for meat eaters.
Bring a pot of salted water to a boil over high heat. Add the fiddlehead ferns and cook until crisp-tender, for about 5 minutes. Drain and rinse in cold water.
Bring another pot of salted water to a boil, and cook the linguine until al dente.
Meanwhile, in a large skillet, heat the butter and olive oil over medium-high heat. Sauté the fiddlehead ferns, scallions, and mushrooms until the fiddlehead ferns just begin to brown. Add the garlic and cook for 30 more seconds. Then, add the lemon juice to deglaze the pan. Add the crushed red pepper flakes and toss well. Season with salt and pepper, to taste.
Drain the pasta and return to the same pot. Toss with olive oil and butter, to taste. Then, add the vegetables from skillet and toss again. Serve on plates and top with the Meyer lemon zest.
