In a small bowl, whisk together the eggs and milk. Add to flour mixture and mix until thoroughly combined.
Slowly add butter, while whisking constantly.
Leave batter to rest for 15 minutes.
Heat a skillet. Melt just enough butter to coat the bottom of the pan.
Pour a soup ladle p of batter for each pancake and rotate pan as you are pouring the batter so it spreads to the edges in a thin layer. Cook until golden brown on both sides.
Serve with sour cream and lingonberry jam or any other berry jam.
Notes
It is very important that the skillet is well heated, but not smoking. Otherwise, the pancakes will stick to the pan.
