@fBoyle-- Yes. Since raw cocoa butter is in solid form in room temperature, it has to be melted before using.
I bake with organic, raw cocoa butter sometimes and I also use it on my skin. For both purposes, I melt the cocoa butter with a double boiler. You could also melt it in a microwave.
Regardless of how you melt it, make sure to use the cocoa butter quickly before it hardens again.
