Chocolate is so personal that I wonder if it's like Brussels sprouts and DNA-related.
Hershey's tastes waxy to me (or did nearly 60 years ago when I last tasted it). I'm a fan of most Lidl stuff - haven't come across those almonds, which sound delicious, but love their hazelnut milk chocolate, also the dark 70% version.
I *think* we had Terry's chocolate orange this Christmas, but am not certain - something similar was handed to me and I ate it.
Steve, I'm told that there's a wall in the Coca-Cola headquarters with taster taps for the Coke sold in different countries; the Irish one is revoltingly sweet compared to some other countries, apparently. They send versions of their syrup to different countries where they'reconstituted into fizzy drink.
