How best to melt and reform chocolate
Chocolate IS tricky to get right, and I have had mixed results using a double boiler, I have also tried using a microwave- ten seconds intervals, checking temperature each time and waiting till the chocolate is good and warm before stirring. I have also used this method- place chocolate in a plastic bag and leave it in a warm sunbeam or outside if it is a warm day until melted, IF you have the patience for this method, I have consistently had good results with this method. In regards to your concerns about air bubbles, I would definetely use either room temperature molds or warm molds, gently banging the molds on your contertop after you add the chocolate will cause air bubbles to rise to the top. I would also suggest letting the chocolate cool to room temperature on your countertop before placing in the fridge to harden. Hope this helps.
