If you have stumbled upon knotweed and want to try it out, this recipe is a simple way to add this unique, foraged ingredient to a spring time dessert.
Japanese Knotweed resembles Rhubarb in texture and flavor, although Knotweed have a distinct earthiness to it. This recipe adds the bright, punchy flavors of strawberry with an additonal kick of black pepper to this foraged fruit cake. Using tradional ingredients is a great way to incorporate wild Japanese Knotweed into your cooking repetoire and seasonal rotation!
Make sure to harvest knotweed when the shoots first emerge in early spring. The plant can grow to be fibourous, think a celery like texture, if you harvest later in the season when the stalks are taller. Young sprouts, sliced into small rounds will bake uniformaly and quickly when mixed with the juice of strawberries.
After harvesting your early spring season knotweed shoots, make sure to use only the bottom portion that does not contain the leaves for any recipes and rinse the stalks well! The instructions below use self rising flour which is a great ingredient to have on hand for any quick bake ups as it omits you having to add the leavening products by hand and cuts down on time spent mixing so that you can get back to exploring new and unique ingredients like knotweed.
