White chips and candy melts are not actually white chocolate, but a similar product where the cocoa fat is replaced with vegetable oil. This allows them to set to the perfect shiny and snappy texture without the lengthy process of tempering white chocolate. They taste very similar, but good quality white chocolate does have a creamier mouthfeel. I used white chocolate so that the nests are soft at room temperature and have a creamy mouthfeel, offset with the delicious crunch from the cereal.
