This dish pairs the almost rhubarb-like tangy qualities of Japanese knotweed with the rich and sweet qualities of serviceberries, a fantastic wild fruit. If you haven’t got your own frozen foraged serviceberries, you can always use frozen blueberries—or frozen wild blueberries, which would be all the better! Serve it hot with a nice local vanilla ice cream, homemade whipped cream, or my favorite, tangy yogurt…
