No worries! This is not bad at all. The reason for this is that the chocolate was not treated correctly during transport or during storage. Due to relatively large temperature differences, the cocoa butter has come to the surface and is there crystallized. This in itself does not detract from the quality of the product, it is even a sign that the chocolate is from a very good quality. However, the white coating makes the chocolate look less tasty, just give it a try. The chocolate is really delicious!
