Droste is Dutch chocolate - it's not available at Ikea. It's Marabou you get at Ikea and they don't have jelly middles Droste doesn't have the jelly in the middle either.
There is a German company who make the jelly in the middle chocolates but I don't remember their name ... I can check at home though as I think I still have some tropical fruit flavour ones left from my German holiday.
In case anyone is interested, the best place to get Droste is the supermarket at Brussels Midi train station (near the Eurostar terminal) they have all the flavours and are quite cheap.
