To melt the chocolate, you can either use/make a double boiler or use your microwave. For the double boiler, boil a bit of water in a pan. Place a glass or aluminum bowl on top of the boiling water, leaving at least an inch of space between the water and the bowl. Break the chocolate into pieces and add it to the bowl. Stir the chocolate every so often till it’s fully melted. If you want to use the microwave, break the chocolate into pieces and add it to a glass bowl with a cube of unsalted butter. Heat the chocolate for about 30 seconds, to start with, but always keep an eye on it (every microwave is different). Take it out and stir. If it’s not fully melted yet, pop it in again for another 10-15 seconds more. Take it out and stir again. If the chocolate gets clumpy, add a bit of vegetable oil to make it smooth and shiny.
