Chocolate Bar Variations

Every few months a new chocolate bar hits the supermarket shelves, hoping to attract our attention. Most recently it was the Cadbury Starbar. Before that it was the Crispello. But how many more variations of the same ingredients do we need? Each new one has its eye-catching packaging and distinctive advertising but they're all just combinations of the same core ingredients:

• Chocolate
• Caramel
• Biscuit 
• Peanut
• Nougat

If I was designing a new bar, I'd come up with a radically new concept. I'd use beetroot and elderflower liqueur and meringue and a dozen other untried ingredients. How successful would that be I wonder?
