Nettles are one of my favorite greens, and one of the most nutritious plants around, so treating them with the respect and care that helps you avoid stings is definitely worth the trouble. I have a thriving nettle patch in a corner of my yard that I don’t routinely have to visit, so I have always harvested the new greens in the spring and then assiduously ignored the nettle patch for the rest of the year. This is partly because I get interested in other things, but mostly because as a child, when I first started foraging to the intense dismay of my parents, my mother wisely bought me a set of Euell Gibbons books so that I would not poison myself. Mr. Gibbons wrote eulogistically about nettles, but cautioned his readers that after the spring flush they develop oxalate crystals and are gritty and inedible. I believed every word he wrote, and so I never tried them after they were about a foot high.
Here in the desert, in the unwatered spot where they have to live in my yard, nettles die back beginning in July, and the stems look dead by September. But this year we got an uncharacteristic long heavy rainstorm in late September, and to my surprise the dead nettle stems began to leaf out again. This week I noticed a mat of fresh nettle leaves, and told myself that no doubt they would be gritty, exactly as Euell had predicted. But I did gather a couple of quarts (using leather gloves) of nettle sprigs and tried cooking them. They were exactly as verdant tasting as the spring greens, and neither gritty nor tough. Now that I know this, I will try to remember to cut my nettle patch back when it dies in the hottest late summer weather, and begin to water in September so that the late fall shoots will be easier to pick.
Cooked greens in the refrigerator are an appetizing snack or light meal waiting to happen. Today I didn’t particularly feel like eating a heavy lunch, but I did want something, and I wanted it to be healthy. I had a cup of blanched nettle greens hanging out in the refrigerator, and half a cup or so of leftover cooked cauliflower rice, so I grabbed two large scallions out of the walking onion patch and picked three large carrot leaves off the last remaining carrots. The garlic that I planted in late summer is sprouting, so I picked one stalk that was about 6 inches high to use as green garlic. The fresh green stuff was chopped and sautéed in butter until cooked through, then the cooked nettles and cooked cauliflower rice were added along with about 2 cups of canned chicken broth and half a cup of heavy cream. You could certainly leave this as a chunky soup, but I decided that I wanted a cream soup, and put the little potful in my Vitamix blender. About a minute later, it was completely creamy and thickened. I poured it back in the cooking pan, added a little water to thin it to a good consistency, simmered for 10 minutes, salted to taste, and ate it with a spoon full of drained yogurt on top to supply a subtle acidic element. The entire process, including grabbing the green stuff from the yard, took about 15 minutes. This is a pretty small time investment for something as absurdly healthy as nettle soup.
Needless to say, vary to suit your own taste. Cooked cauliflower is a surprisingly good creamy thickening agent, and if you are vegan you could use olive oil for the initial sauté and vegetable broth for the cooking liquid, and leave the cream out or substitute nut milk. It could be finished with a few drops of lemon juice instead of drained yogurt. Vegetarians can change the broth and leave everything else the same. As written it is a delicately flavored and very comforting soup, perfect for days when fate is being unkind, but if you want something more emphatic you can start playing with herbs. If you don’t happen to have a nettle patch, use some other leafy green. Have fun in your kitchen and make the result work for you. My mother objects to my greens soups on the undeniable grounds that they are green, but if you have a prejudice against the color green in food I do hope that you will get over it, because it is the marker for some of the healthiest food that you can possibly eat.
And by the way, Euell Gibbons wasn’t right about everything, but his foraging books are still well worth reading for their palpable joy in the outdoors. In one plant essay he says that wild foods are his way of taking communion with nature and the Author of nature, and I think this sums it up.
