Let's be truthful. Cadbury chocolate products are pretty awful. Pure Cocoa retails at about £18/kg - it's expensive. Which is why British chocolate contains as little of it as possible; it's a nasty profit maximising product that melts on your fingers at room temperature, whilst real chocolate does not. It's mixed with a host of cheaper fillers, chiefly sucrose, to bulk it up and it tastes like sewage sludge.
If you like chocolate, try Charbonnel et Walker. This is chocolate that will fire off taste receptors you didn't realise you had. Cadbury's Dairy Milk shouldn't even have the right to use the same name. When I unpacked 500g of cocoa the other day, the entire kitchen was filled with a rich, sensual, vanilla-packed saliva-inducing scent of cocoa powder ground so fine as to be explosive; whisked with scalded Jersey milk and Demerara sugar as a bedtime drink as you snuggle under the goose-down quilt, it beats (most) sex.
No, Cadbury and Kraft are a good match; makers of plastic artificial cheese, and makers of cocoa-flavoured artificial chocolate. Sorry.
