I remember my mum doing that with her sisters in law. And my grandma. It was always a big project. They also got together to make lefse. They made two kinds, one from potato and one from corn meal. They’d bring their lefse grills and special flat wooden sticks for turning. I think it tapered off after my grandma died in the 70’s. mum still made lefse until about 15 years ago. Just small batches. Now we buy it from the church.
