Way back in 2005, Cybele reviewed Orange Creme Hershey's Kisses at Candyblog. The orange-flavored white chocolate kisses didn't last too long at the time, but Hershey's has just re-released them, labeled as a "limited edition" offering for their year-long 100th anniversary celebration.
The original review noted - and I completely agree - that these chocolates taste a lot like orange creamsicles in the way that they blend orange and vanilla. The chocolate has a tempting orange scent and melts into your mouth smoothly and easily when you bite into one. Unfortunately, these kisses also have an almost overpowering sweetness to them that makes it difficult to eat any more than one at a time without having something to wash them down with.
The concept for these kisses is a good one. I'd try mixing these up with dark chocolate kisses (or other dark chocolates) for some variety and to subdue the sugar.
The bag makes no mention of how long the release will last, but I wouldn't be surprised if they stick around at least until Easter at the beginning of April.
