I have often marveled (and gotten hungry) at the beautiful pictures in the blog Smitten Kitchen. It documents mostly baking recipe, and chocolate spreads, ganaches, and pure molten chocolate are often present. On the the blogger's pictures, it looks glossy, shiny and yummy. It is smooth, but has a discernible texture caused by the pouring/spreading. See for example this chocolate peanut butter cake post, and the chocolate stout cake post.
The only time I tried to photograph chocolate, I ended up with
Note that it had looked just like hers in my kitchen (this is very dark chocolate, probably 85%). I also made sure that the white balance is more or less correct (that's what the white t-shirt in the corner was for). The color is still unappealing, and the surface looks terrible. (I am aware that the composition and the smearing of the chocolate on the glass bowl are a bad idea, but assume that I will avoid them next time).
How could I have made it silky-smooth and mouthwatering instead?
