Whatever happened to Mon Cheri hazelnut chocolates?
I believe they were discontinued around 2008. In the US Ferrero Mon Cheri were just the hazelnut filled variety. There were issues in some states with importing the liquor filled Cherry version, so they created an American-only variety.
Then about three years ago they introduced Ferrero Kusschen in Europe. They're little foil wrapped pieces filled with hazelnut cream and chopped hazelnuts (they come in a milk and dark variety). They're hard to find in the US, but you may be able to locate a gift pack at an import store or perhaps duty free shops at the airport.
