Saying that, missus was given a tub of Heroes tonight by someone at work..
Having just ate 3 mini Twirls from the tub.. then a normal bar of Twirl.. there is definately two differentiations of chocolate recipe used here..
Normal twirl bar = Cadbury's taste..
Heroes mini version = Utter tasteless shit and nothing like a Cadbury taste.
So conclusive a different recipe is used and a much cheaper shite one at that too.
Just been to Tesco and did an experiment on the Caramel too..
Again, nasty cheap chocolate is used in tubs of sweets it seems differentiates to the retail bars on our shops shelfs.
