Non-Alcoholic Mulled Wine

Just a quick one - a colleague just fed me some of this, and it was great!

- 1 carton cranberry juice
- 1/2 carton orange juice
- sugar
- Mulling spices (she used ready-made, but the usual cinnamon-cloves-ginger-nutmeg will be great)

Heat it all up. Leave to infuse for a bit. Reheat and serve. Great for people who have to drive home.
