Lefse Enjoyed year-round, these soft flatbreads are especially common during holidays. For many Norwegians, and members of Norwegian communities such as those in the Midwestern United States, making lefse symbolizes the start of the Christmas season. They can be either sweet or savory: On the Christmas Eve buffet, they often accompany lutefisk (preserved cod) and pork ribs, but as a snack, they're popular rolled up, spread with butter, and sprinkled with cinnamon-sugar. Lefse are traditionally made using special grooved rolling pins; large, superheated griddles; and long wooden spatulas. However, we found that a regular rolling pin, a 10-inch cast iron skillet, a pastry bench scraper, and a thin metal spatula worked just fine. Cooking the potatoes thoroughly and using a ricer or food mill will ensure that there will be no lumps in the potato dough.
