Lefse is a traditional flatbread, visually looking like a huge, round tortilla. It comes in many varieties such as plain, sweet, thin, or thick. There is also a popular version of lefse with potatoes incorporated in the dough, and it is a favorite of the Telemark region.

Originally, potatoes were not included in the flatbread since potatoes were introduced to Norway just about 250 years ago. Today, lefse is usually dipped into a bowl of water to absorb it, and is then consumed with butter, cinnamon, and sugar. For serving, it is recommended to roll the flatbread and cut it at an angle.

All of the lefse varieties can also be used to make appetizers or sandwiches, when they are filled with cheese, salad, seafood, or meat. Potato lefse is especially good for canapés due to its unique flavor. In Norway, lefse can be bought at most supermarkets or baked at home, and it is also popular in the United States of America, in cities with high percentages of Norwegian ancestors such as Minnesota, North Dakota, and Seattle.
