Hershey's - bleeeech

To give you a heads up on Hersheys. They have move some of their production to Mexico and have let some of their US workers go.
I now look on the label to see where the chocolate was produced. It might not say Mexico but it doesn't say US either.
There may be some connection with your observations.

You know what this is...they use different fat products in the UK and US for chocolate. I don't know if it's a legal issue or a melting temperature issue (could be both), but that's why they taste different. (My Grandfather was in the candy business).
