At Riverbend House in Cochecton, NY this past weekend, Owens, the sourdough bread baker, lifelong forager, and James Beard Award–winning cookbook author, led a foraging and baking workshop on the banks of the Delaware River. Between intermittent rain showers, she walked us to the riverside, where we spotted freshly unfurling fiddlehead ferns, careful to harvest only the bright green species and not the furry white ones. We spied young shoots of Japanese knotweed, a stalky invasive species that cooks sweet and tart like rhubarb. As we passed through the cemetery, munched on our petite raw greens, we saw what we'd come for. Carpeting the forest floor in little patches, the floppy, green, bunny-ear-shaped leaves were instantly recognizable.
