Spring has officially sprung, and I was so tickled to take my first little stroll down to the forested wetlands at the nearby Reed College campus during an early break in the vernal rains. This time of year is my chance to shake the last of the doldrums of the wan winter pallor, to ditch some of the root vegetable stodge and to taste the first bosky flush of the equinox.
I was delighted, then, that my proposal to prepare a nettle-based dinner was sponsored by Foodbuzz. Having spontaneously submitted my idea as a sudden burst of inspiration, I'm thrilled that our friends at Foodbuzz wanted to help me share it with the food blogging community for the March 24, 24, 24 event.
Although I am a botanist by training (and the trade pays the bills), I take so much pleasure in my city life when I'm off the clock. I love going out to fancy dinners with Scott, going out for a movie or to see a favorite band. But I especially love putting on some hot pink lipstick, a skirt and heels and hitting the bars with my similarly city-loving girlfriends. My girls like good food, but don't necessarily love the idea of grubbing around in the swamp to pick their ingredients.
Stinging nettles (Urtica dioica) grow in swampy places and riparian corridors along streams throughout North America, Europe, Asia and northern Africa. They resemble a mint, though they're in their own botanical family (the Urticaceae). They're easily identified by their pairs of deltoid (slightly triangular), dentate leaves (opposite-decussate in orientation) with fine spines covering the stems and leaves. In the Pacific Northwest, March is when they first poke their little heads out of the alder and cottonwood duff in search of spring's first warming sun. This time of year, too, is when they are at their most tender and nutritious. Nettles are an excellent source of protein, iron and vitamins C and A.

True to their moniker, they do pack a potent sting, delivered mercilessly by the fine, silicate trichomes which act as tiny syringes. The sting comes from the combination of histamine, serotonin and formic acid (similar to the venom injected by stinging and biting formicine ants). The pain is a sharp, tingling sting, and on my skin, leaves small white bumps with reddish swelling. To avoid this, always wear gloves when picking, use a salad spinner and tongs to wash, then blanch the greens in salted water to neutralize the venom before eating.
Rather than haphazardly add nettles to ordinary foods to bolster their nutritional content, I really wanted to showcase the nettles as a primary flavor in a variety of dishes. I put together a menu that would spotlight the stinging nettle in myriad ways:
mixed greens with Granny Smith apples, crumbled smoked fontina and honey-nettle vinaigrette
lamb steak and pan-roasted baby potatoes with nettle pesto
nettle gratin with Pecorino and nutmeg cream

I was initially going to make a dessert (not using nettles - this isn't Iron Chef for fuck's sake), but Greta had cardamom molten chocolate cakes with ginger-rum ice cream waiting for us at her place, and who can really argue with that? No one, that's who.
