Fiddleheads are the young curled up sprout of an ostrich fern. When properly prepared and cooked, they are meaty, with a slight crunch, similar to asparagus with a unique flavor. The first thing you need to do when you get fiddleheads is to clean them well. Fill a large basin with water and soak them, then rub each fiddlehead to remove the brown leafy fronds. Drain and then spin to dry in a salad spinner. Think asparagus when you prepare them from here. You can steam them and toss them in butter. Sauté them with olive oil and garlic. You can also make many other preparations.
I make a light Camembert cheese sauce (don't think Alfredo!) and mix it with as many spring delectables as I can get my hands on. Fiddleheads are always front and center as long as they're available.
Melt the butter in a medium-sized saucepan over medium heat. Then, add the flour and cook for 1 minute. While whisking, add the wine, then milk and cream. Bring to a boil and let thicken. Turn off the heat and mix in the cheeses. Season with salt and pepper, to taste, and set aside.
Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until al dente. Drain. Toss with the butter and set aside.
Heat a large sauté pan over medium heat. Add the oil, then the garlic, and sauté briefly. Add the cooked vegetables and sauté until well heated. Deglaze the pan with the white wine and then add 3 cups of the reserved sauce. Add the pasta and toss. Serve with Parmesan and season with pepper, to taste.
