1. Place all the spices and maple syrup into a saucepan.
2. Pare the rind off the lemon and orange and add to the pan.
3. Pour in about 50ml of red wine and bring all the spices up to a simmer, stirring to combine the maple syrup and so the spices begin to release their aromatics. After about five minutes, turn the heat right down and add in the rest of the wine.
4. Allow to warm on a low heat for about 15 minutes. You want the wine to be warmed through and gently simmering to take on the flavours, but not bubbling or boiling.
