To buy chocolade sauce is expensiv and it comes allways in to small flasks. But it is very easy to prepare homemade chocolade sauce. I make my chocolade sauce always with this recipe, it is easy, fast and cheap.
In 5 minutes I have about 200ml chocolade sauce that cost me not more than 1 Euro and I use fair traded organic incredients. The sauce taste like dark chocolate and you can store it for serveral weeks in the fridge.
