Punschrulle

Punsch-roll is a Swedish small cylindrical pastry covered with green marzipan with the ends dipped in chocolate, with an interior consisting of a mix of crushed biscuits, butter, and cocoa, flavoured with punsch liqueur. This pastry is often called dammsugare (lit. 'vacuum cleaner'), referring not only to its appearance, but also to the supposed practice of the pastry baker collecting crumbs from yesterday's cookies for filling. Other names are arraksrulle (as arrak is an ingredient in punsch) and "150-ohmare" (lit. '150-ohmer'; because a brown-green-brown colour sequence on a resistor denotes a resistance value of 150 ohm). A similar pastry in Denmark is called træstamme (lit. 'tree trunk'). These however, are usually not colored green and no liquor is added to the cookie butter.
