I'm planning to dazzle some friends with a white chocolate fondue like one I had many years ago at the fabulous Swiss restaurant in the Swiss centre. I have attempted this before but found the quality of white chocolate that I used (supermarket variety) tasted more like cake topping than anything else. I havent made one in a very long time due to an inability to locate good white chocolate. Does anyone know where I might find some in London? Failing that if you have other suggestions for dessert fondues I would love to hear them.
