Stinging Nettles

The lightest touch shatters them and unleashes a poisonous brew of neurotransmitters, histamines, and formic acid, the same acid that makes bee stings and ant bites so painful. The smart thing is to avoid stinging nettles altogether.
Unless you want to eat them, that is.
A quick blanching neutralizes their sting, and when cooked, nettles have a robust, almost meaty flavor. The leaves are high in calcium and iron, and studies have confirmed their effectiveness as an anti-inflammatory, a use that goes back to ancient Greece.
Stinging nettles (Urtica dioica) grow throughout North America, but are especially abundant in the wet coastal forests of the Pacific Northwest. Anyone who’s inadvertently stumbled into a patch remembers what they look like, and it’s easy (if painful) to test a leaf to make sure it stings. Bring along an experienced forager if it’s your first time out nettle-gathering, wear a good pair of gloves, and don’t collect any if the nettles have flowered or gone to seed. After that point, they develop bits of calcium carbonate which may cause urinary-tract irritation.
You might be lucky enough to find foraged nettles at your local farmers’ market during the spring and early summer. They often grow in the same places where morels are gathered, so ask your local mushroom pickers, too.
Once you’ve gathered your nettles, bring a big pot of water to a boil, drop in a few handfuls (use tongs or wear gloves), and cook them for a minute or two to get rid of the sting. Drain them in a colander set over a bowl to save the liquid, which makes a great vegetable broth. Squeeze the blanched nettles to get out as much liquid as possible. I put those baseball-sized squeezed handfuls in sandwich bags and freeze them.
Using stinging nettles instead of spinach adds extra umami to this nettle artichoke dip.
