Caramel filled chocolate sweets from Scandinavia - made by Cloetta.  Ever heard the term "Do you love him so much you'd give him your last Center Rulle"?  No, well, nor have we, but these are basically like Rolos, but with a much nicer chocolate and a smoother caramel centre.  It is entirely possible to finish a pack in under three minutes flat, even without giving any to the person next to you.

These are made for you.  Not for sharing.
