For milk chocolate, either Ritter Sport (the pale blue pack), or Milka.
Milka used to be amazing, especially the creamy stuff. Unfortunately, guess who now own it....
I heard that the Irish-made DM is still made to the old recipe (that they claim hasn't ever changed....). You can buy it on eBay - from some enterprising sellers in NI, so standard UK postage rates and no import charges.
It must have saved them an absolute fortune ruining the wonderful legacy they bought by switching the recipe to using rubbish ingredients - enough that it's worth their while gaslighting whole generations that it's unchanged and, presumably, counting on the younger ones never knowing any different.
I'm not suggesting that they've done anything actually illegal (would have been if I were in charge
), but by way of (sort of) parallel, I often think when you see some of these shady businesses - dodgy mechanics and tradesmen etc. - that run such a professional, labour-intensive, incredibly-organised set-up in scamming people and having to keep a permanent eye over their shoulder for the police (and Matt Allwright!) and being prepared at all times to do a moonlight flit.... wouldn't it just be a whole load easier and less stressful all around to put all of that effort into running it as a legitimate, honest, respectable business instead?!
