When I was a teen my first husband's Norwegian grandparents taught me to make this thin, potato pancake. The recipe is delicious, of course, but the most wonderful thing about it was their tradition of making it as a family. Over 20 years later, I'm still using Gramma's handwritten card, but am finally posting this dear to my heart recipe for ZWT-6. The mashed potatoes must be completely cold before adding the flour or else the mixture turns to paste, so I like to make them the night before & refrigerate overnight. The lefse rolling pin, with it's deep, checkerboard grooves and the lefse turner are traditional tools, but the pancakes can easily be made with a regular pin and spatula.
