Mulled chai cider

Method

1. Put the cider, apple liqueur (if using), teabags, 2 tbsp of the brown sugar and half the pared orange and lemon zest in a saucepan. Bring slowly to the boil, stirring, then simmer very gently for 2 minutes.
2. Remove the pan from the heat and leave to cool for 15 minutes (see Make Ahead). Taste and add more sugar if you like a sweeter taste, then serve in heatproof glasses (or mugs) garnished with apple slices and the remaining zests.
