Pour the cider into a large pan on a low heat and let it warm through for a few minutes. Add all the spices and juices and turn the heat up. Once boiling, turn down to a simmer and leave to tick away for 5–8 minutes.
As everything infuses you’ll get delicious layers of flavour. Taste it and add sugar as you like. You don’t want it sweet; you just want the sugar to join the spices in a harmonious taste. When you’re happy with the flavours, ladle into glasses or mugs and serve warm.
