For filling, beat together cheese, eggs, sugar, and flour. Mix well.

Using a small jug, pour 1/4 cup of the batter into pan, swirling the batter evenly around the pan. coo the batter over moderate heat until lightly golden. Remove from the frying pan, golden side up.

Heat butter in the pancake pan and fry the blintzes until golden brown on both side. To serve, arrange the blintzes on a serving plate and spoon on the sour cream.
