The secret to not burning the chocolate is to take it away from the heat before it's completely melted, and keep stirring until it is. When you melt chocolate on the stovetop, place it evenly over the bottom surface of a heavy saucepan over low heat. Again, remove the pan from the heat before the chocolate is completely melted and stir: in less then a minute, the chocolate will be smooth and silky. Also, be sure all your utensils are dry: even the tiniest bit of water can cause the chocolate to seize (turn hard and grainy), leaving you with a dull, hard clump of chocolate. Some recipes call for melting the chocolate along with butter or cream, which helps prevent scorching as well.
More often than not, I melt chocolate in my microwave. (I sometimes think that were it not for melting chocolate and butter, I would never use it!). Place the chocolate in a microwave-safe shallow dish (Microwave-proof pie plates are ideal) and microwave at 50% power (medium heat) for 2 to 3 minutes or until it's soft enough to stir smooth. To be on the safe side, start checking at about 1 1/2 minutes.
