My daughter turned 9 this month.  One of her birthday gifts from a friend was a tin of KitKats.  But not just normal KitKats, these are from the UK in a collectible change bank.  Fun!  After opening them up we noticed they looked different.  Then my daughter ate one and said they tasted totally different than "normal" KitKats.  So last night we pulled an old KitKat out of her Halloween bin and did a side by side taste test.  She was right!  They do taste different.  We preferred the taste of USA KitKat even though the UK version looked better, melted more like real chocolate and tasted like it was made with more natural ingredients.
