Sadly, as everyone knows by now, Droste has discontinued the chocolate apples. However, a company called Terry's (a division of Kraft Foods) imports the chocolate apples and oranges from a company in Poland and sells them at World Market/Cost Plus stores. I imagine you also could get them on the website: www.terryschocolate.com
They are very good. Not quite as good as I remember the ones from Droste, because the Terry's chocolate is a bit sweeter and less creamy than Dutch chocolate, but still very, very tasty and much better than your average Hershey bar.
