There’s nothing like a little urban blight to produce an excellent salad. While not impoverished (not unless you consider dilapidated $600,000 bungalows a sign of destitution), our neighborhood ain’t exactly Beverly Hills, meaning that in terms of landscaping it’s a little rough around the edges. And the edges–parkways, cracks in the asphalt, neglected plantings were, on this warm February day, overflowing with weeds. Edible weeds.
We explored these edible edges this afternoon with visiting Chicago artist Nance Klehm, who proved that many of these weeds are not only edible, but tasty, in a lecture and food foraging walk she led that was sponsored by the innovative art space Machine Project. Gathered on the walk were wild mustard, mallow, shepherd’s purse, dandelions, oxalis, prickly lettuce, lamb’s quarters and a lemon and orange found overhanging the sidewalk, all of which made for a large and delicious salad.
A highlight was a front yard overflowing with lemony oxalis (Oxalis deppei, pictured on the right behind the chain link fence. Oxalis is sometimes known as Iron Cross Plant because of the shape of its leaves–see the Plants for a Future Database entry on Oxalis for more information). It’s a relative of sorrel, which we have growing in our garden and has a similar taste. Oxalis contains vitamin C, but also contains oxalic acid which can interfere with calcium absorption, though you’d have to eat vast quantities to have an ill effect.
At the end of the walk the class mixed up and shared a bowl of our findings. Klehm will be teaching three classes in February and March: cheese making, fruit wine and vinegar, and pickling. Clickulate here for more information.
