Why does chocolate turn white after a long time?
If you’ve kept a bar of chocolate in your cupboards for a long time, you might have noticed that it gets discolored. It looks like a white shadow has covered the chocolate, and it doesn’t look appetizing anymore. However, it’s nothing to worry about, and you definitely shouldn’t throw the chocolate out since it’s perfectly safe to eat. It’s just that through time, liquid fat like cocoa butter migrates through the chocolate and crystallizes on the candy’s surface.
