White chocolate coating for cakes, tarts or biscuits consists of white chocolate with a cocoa content of about 28%. It contains a lot of sugar and cocoa butter as well as whole milk powder. White couverture tastes very mild and sweetish. It is best to store them in a cool and dry place. White couverture gets a nice shine if you melt only two thirds of the couverture and then stir in the last third and briefly heat it again.
