Although it is believed to have originated in Persia (present-day Iran) and to have been introduced to Europe through the Turks, there is some dispute between Hungary and Italy over its origin. Marzipan became a specialty of the Baltic Sea region of Germany.
In particular, the city of Lübeck has a proud tradition of marzipan manufacture (Lübecker Marzipan).
This Niederegger marzipan 'long' bar is flavored with strawberry and chili covered in dark chocolate. They also have a cranberry marzipan. Lubeck has gone wild. Carstens is another good Lubeck marzipan company.
Sweden and Finland also refer to a marzipan that contains 50% ground almonds, a much higher quality than regular marzipan.
Danish Marzipan maker Anthon Berg uses pairings like plum and maderia to make it's already fantastic melt in your mouth marzipan truly sublime. I don't know what the difference is with these pattys or if it's the same formula as in their regular bars. It tastes different to me. Upon reflection I would guess it the fruity filling that keeps the marzipan softer. So so that you can swish it around in your mouth right after you take a bite-before you have even chewed it!
