Finnish Pancake

In a blender, mix:
4 eggs
3/4 cup flour
1/2 tsp salt
1 tsp cardamom
2 tablespoons sugar
2 cups milk

Preheat oven to 450 degrees. Melt 4 tablespoons of butter in a 9 by 13 inch pan.  I do this by putting the pan with the butter in it into the oven as it preheats.
Pour in the batter (will be very thin).
Bake for 20 minutes.
It will puff up  but will collapse as it cools.
Great with fresh fruit or jam or syrup.
