Peel and cook potatoes until well done. Then, mash cooked potatoes while still hot, and add lard, butter, salt, and cream. Mix ingredients together until smooth. After potato mix has cooled down, add 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 degrees F or more.
Remove dough from refrigerator, and roll onto 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 then 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 after 6th one has been placed on top. When finished let cool before packaging.
Serve with brown or regular sugar or butter. Add a thin slice of meat instead of sugar or butter for something different.
