"The most famous product is the "Halloren-Kugeln", or Halloren globes, which receive their name from the early salt workers, whose buttons the chocolates resemble. The brand was especially popular in Communist East Germany and remained popular after reunification." (source: http://en.wikipedia.org/wiki/Halloren_Chocolate_Factory)
So apparently we are dealing with something quite special and historic here!
I loved the presentation of these chocolates, they come in a little tray with a paper insert that makes them look quite special:
The Kugeln have an interesting shape (thanks, salt workers ;)) with a sweet irish cream aroma. I hate to sound like some marketing type person, but they really are the perfect size and shape for popping in your mouth. Biting into one of the Kugeln, I was met with a very intense sweet hit. The filling was some kind of fondant, with half irish cream and half plain fondant. The two were indistinguishable and it all just tasted very sweet, with a hit of irish cream. I can't comment much on the chocolate coating as it was just standard milk chocolate, and the sweet filling overpowered it.
Overall I'm not sure what to think of these Halloren Kugeln. They are certainly a unique product, and kind of addictive, but yet so sweet you can't eat too many at once. I think they're worth a try if you see them. According to the Halloren website they make a dizzying array of products, with many different Kugeln flavours including plum-rum, apple & cinnamon, black forest, and seabuckthorn (!). Hopefully some of those will also find their way into 99p stores!
