This is considered a buttery cookie but looks like a miniature tart base. Sometimes it is eaten just plain without anything in it. Sometimes it is filled just before eaten with whipped cream and fruit or jam. It is normally pressed into tiny fluted tins. Tiny muffin tins would probably work just as well. My DBIL was born in Norway. He loves many of their heritage foods. This is one of them which my sister makes every year at Christmas time for him. I think if I remember correctly the name means 'Sand Tarts'. Posted for ZWT 2010. Preparation time does not include refrigeration time.
