i sometimes have trouble melting chocolate. I don't use a microwave....i put it in a bowl over a pan of boiling water. Sometimes the consistency is just wrong. Is it the chocolate or am i doing something wrong?

Use a good quality chocolate - the higher the cocoa percentage the better - and make sure that when your bowl of choc sits over the boiling water that no steam or water gets into the mix....this will ruin the chocolate. keep the water on a very gentle simmer and stir the choc gently til melted.
