White candy coating is my secret weapon when I want to dip truffles in white chocolate. I hardly ever have enough white chocolate for tempering, so instead, I whip out a back of Merckens coating! This brand is my favorite--it has a really fluid melt and produces a nice, shiny coating that's not too thick and not too thin. (If you need a bright white color, I recommend Wilton's brand candy coating melts).
