I got a panettone for Christmas, which had a dark chocolate frosting with milk choc flakes on top, and dark choc streaks throughout the actual cake. I tried it, and...felt sick afterwards. Ew. Didn't finish it, when I usually love panettone with chocolate in it.
Oh, and I also got a David Jones "Popcorn Medley" thing - popcorn covered in choc. Milk, white...and dark. I threw away the latter; the other two are surprisingly good.
I also prefer milk chocolate, but the quality of dark chocolate depends on the brand and the percentage of cocoa: e.g. Lindt's swiss dark chocolate is good even with high percentages of cocoa ( 70%/90%). Wow, are you also eating our panettone? What a nice surprise, I thought it was not known there.
