Melting chocolate chips is easy, even if you don't own a double boiler. You can make your own make shift double boiler with a heat-safe glass bowl and a sauce pan on the stove. Add a couple of inches of water the the saucepan and place the bowl on top. Fill the bowl with chocolate chips. Heat until the chocolate is melted, stirring regularly. An even easier way to melt chocolate is in the microwave. Just heat the chocolate chips in 30 second increments, stirring after each one, until the chocolate is melted and smooth.
