The chocolate can also be melted in the microwave. To do this, chop the chocolate finely, put it in a microwave-safe bowl and set the steam oven to "microwave" mode 100W. Melt the chocolate in 20-second steps, stirring in between each time and starting the process again. As the white chocolate can burn quickly, a slow melting process is required. This takes about 1 1/2-2 minutes in total.
