Add a few tablespoons of vegetable oil to the chocolate to give it a nice shiny coat. A microwave is another good way to melt chocolate, and it's easier than using a double boiler. Place chocolate chips in a glass dish and top with two or three tablespoons of vegetable oil. Set the microwave to defrost, or 30 percent power, and heat the chocolate for two minutes. Stir and heat until melted, stirring every two minutes and keeping a close watch on the chocolate.
Wooden spoons retain water, which is the enemy of melted chocolate.
Use a rubber spatula to stir chocolate. Keep the bottle in a bowl of hot water to keep the chocolate from hardening. Once the chocolate is melted, it can be poured into any number of molds, such as a flexible plastic ice-cube tray. Chill molds in the refrigerator for approximately 30 minutes before adding chocolate. After pouring the chocolate into a mold, add toppings such as nuts, cherries or marshmallows.
