Very good ones mentioned so far, especially Kitkat ( 1935, Yorkshire, Rowntree UK), Jelly Belly Beans (1976, Alhambra, California, USA) and Toblerone (1908, Bern, Switzerland, Europe).
But my personal faves are:
Jelly Babies (1919, Sheffield, Yorkshire, UK - originally called 'Peace Babies'??) Which are divine. The best kind are the traditional Bassets ones. But there is a version available by weight in sweet shops, that has no artificial colouring or flavouring and is very delicious indeed.
Quality Street (1936, Halifax, UK) which just remind me of childhood Christmasses and coloured sweet wrappers under the Christmas tree, happy families and being given my latest torch!! (Usually a single AA cheap plastic import with bezel mounted Santa Claus or Snowman face, but normally my favourite prezzie!!!)
Walnut Whip (1910 Edinburgh, Scotland) Which was always a treat for a special occaision and not a sweet for everyday. At least until I found out where my Mum kept her secret stash!!
I've realised that all my fave's come from childhood and none from my adult years. I suppose that is significant, seeing as my torch desires also stem from those formative years.
Long live the candies, old, new or to come.
Be lucky....
