I start each and every day with half of a trader joe dark chocolate bar. It is the first thing I do in the morning. They are made in Belgium and I have heard by a very respected chocolatier who does private label for TJ. They come in a 3 pack and are very good. If having milk chocolate I will go for Lindt. Love Perugina Baci too.
Cooks Illustrated did a chocolate chip blind test and I think Guittard won. Or maybe it was Ghirardelli.
