Peel and cook potatoes until well done. Then, rice while still hot and add the butter. Mix ingredients together until smooth.
After potato mix has cooled down, add, salt, sugar, cream and flour and mix with hands (if dough feels too soft, add flour or if dough feels too hard add cream.)
Form dough into a long roll or a round ball about the size of a tennis ball. Place into the refrigerator. Heat griddle to 450° F. Remove dough from refrigerator, and roll on well-floured cutting board until thin.
Use a lefse stick or a long spatula to move the dough to the griddle. Watch closely, and when the sheet is bubbly all over, flip over and cook the other side. (You may turn more than once to get the correct browning.)
Place the cooked lefse on a cloth and cover with another cloth. Add lefse in stacks of 6 and turn over to cool after 6th one has been placed on top. When finished let cool completely before packaging.
Serve with brown or regular sugar or butter. Add a thin slice of meat instead
of sugar or butter for something different.
