I usually put some amount in a cup and add a very small amount of water to start mixing. This is usually effective as long as the amount of water is very small compared to chocolate, in which the chocolate still has a strong taste. I thought of using milk, but I do not want the chocolate's taste to be faded (milk has a taste compared to water being neutral ).I also tried using the microwave, but that was pretty useless.
I want something really fast and reliable.
