With these buns I would be dragging a parallel between cultures. In my area, Lucia buns are called Luca buns and more like without saffron... :-) We use cheese and salt instead, and they have a different meaning. Those eye shaped Lucia buns are sweet and all about illuminating the day which is the shortest day in the year. The other ones are salty and served to relatives - for the living and for those who passed away. The nickel in the bun brings the richer upcoming year for the one who finds it.
