Red liquorice In many countries there is also a product sometimes known as red liquorice (red licorice), which is extruded in a way that resembles liquorice strings but is made with flavourings other than liquorice, such as strawberry, cherry, raspberry, or cinnamon. More recently, products have been introduced in a wider variety of colours and flavours, including apple, mango, blackcurrant, and watermelon. While the common name for these confections has become "red liquorice" or often simply "liquorice", they do not have the taste of liquorice. "Black" in "black liquorice" would formerly have been redundant, and has become a retronym in North America.
