Pareve batter: 2 cups water, 2 eggs, 2 cups flour, 1 tablespoon corn oil, 1/4 teaspoon baking soda.
Filling: 1 1/4 pound of farmer cheese, 2 tablespoons flour, 1/2 teaspoon salt, 1/4 teaspoon fresh black pepper, 1 egg.

Make wrapper batter:
In a blender blend wrapper batter ingredients and let stand 30 minutes. Add baking soda in a last minutes before frying.

In an 8-inch skillet, preferable non-stick, melt a butter over moderately high heat. Pour in enough batter (approximately 1/4 cup) to just coat the bottom of skillet, swirling, and cook, undisturbed, until top is set and bottom in golden (do not turn wrapper over).
Transfer wrapper to paper towels in one layer, golden side up. Make more wrappers with remaining butter and batter.

Make filling:
In a food processor, blend cheese, salt, pepper, egg and flour.

Put 2 tablespoons filling in center of each wrapper and fold opposite sides of wrapper over filling until sides barely touch. Fold in ends to completely enclose filling, forming packets. Make more blintzes with remaining filling and wrappers. Fry blintzes until golden brown, 5 to 10 minutes.
