Add color to an herb garden with these annuals, which are closely related to violets and enjoy similar growing conditions. Harvest their large flowers for pretty desserts. Brush delicate buds with egg white and dip them in sugar for a candied effect that will enhance their grassy, wintergreen flavor. Then, top an iced cake or a batch of cupcakes with the sweet garnish. If that's too sweet, dress a salad with bare pansy petals for a splash of color against green.
