Wawel - ORZECHOWE

 It's one of the less-popular Wawel sweets, but still well-known. It's covered with a very tasty, milk chocolate.

 The filling is made of hazelnut cream - quite as hard as the chocoalate, but melts a bit quicker.

The taste of the whole thing is bitter-sweet because of the hazelnut cream. The nut taste is very strong and natural. I didn't like it when I was younger, because I prefered the Nutella-like things. Now it's quite ok. Not 100% my type, but still :)
Oh, it has some hard crumbs, or something inside - I'm not sure what can it be, cause the pieces are little as dust.
