Pretty on the plate, this salad of delicate greens contains bright, juicy, tart sorrel; crisp radish; and delicate bachelor’s buttons. Despite the blue, pink, and purple hues of bachelor’s buttons, also known as cornflowers, their flavour is fresh and green. The dressing comes together with a bachelor’s button vinegar made in advance by infusing the flower heads into apple cider vinegar for a bright, subtly sweet flavour. If you can’t find bachelor’s buttons, you can use nasturtium or violas.
