OK. So I am going to give you the low-rent way I do it. It is Ina Garten's method and it works really well. Not sure how a microwave timer can be wrong, but anyway, she says, "Place 3/4 of the chocolate in a glass bowl and place it in the microwave on high power for 30 seconds. (Don't trust your microwave timer - time it with your watch.) Stir with a rubber spatula. Put it back in the microwave for another 30 seconds and stir again. Continue to heat and stir every 30 seconds until the chocolate is just melted. Immediately, add the remaining chocolate and allow it to sit at room temperature, stirring often, until it's completely smooth. (If you need to heat it a little more, place it in the microwave for another 15 seconds at a time.)" I hope this will work for you. Good luck!
