Dark chocolate is my favorite... of course, the Hershey Nuggets are my favorite format and a good choice for the budget conscious, but Hershey miniatures are cheaper by the ounce than those, and the selection (at least in the mixtures) are the same. The Special Dark is available as a single big bar, as well as bags of nuggets in the regular grocery store as opposed to the warehouse clubs.
Hersheys Special Dark was my introduction to dark chocolate. Since then I’ve found many many dark chocolates (thank you Trader Joe’s) and have learned that HSD is hands down the worst dark chocolate. And yet, I still love it.
