"If there is one flavour that instantly transports me to Christmas day it is the humble clementine as I always find one at the bottom of my Christmas stocking. The bitter chocolate is sweetened with a delicious homemade clementine syrup. If you have spare clementines, increase the syrup quantity and use the extra in prosecco or Champagne for a festive cocktail. Exert by Hannah Miles in her cookbook, "Hot Chocolate".
