Making delicious blintz might seem challenging, but following these steps will make it easy:

1. Prepare the Blintz Batter: In a mixing bowl, whisk together the flour and eggs. Gradually add milk while stirring until the batter is smooth. Blend in the melted butter and a pinch of salt.

2. Cook the Blintz Wrappers: Heat a non-stick skillet over medium heat and lightly grease it. Pour about 1/4 cup of batter into the skillet, swirling to cover the bottom. Cook for 1-2 minutes until the edges are set and the surface is slightly dry. Flip and cook for another 30 seconds. Remove from the pan and repeat until all batter is used.

3. Prepare the Filling: In a separate bowl, combine ricotta cheese, sugar, vanilla extract, egg yolk, and lemon zest (if using). Mix until smooth and well combined.

4. Fill the Wrappers: Take one of the cooked blintz wrappers and place about 2 tablespoons of the filling near one edge. Fold over the sides and roll up to encase the filling completely.

5. Cook the Filled Blintz: In the same skillet, place the filled blintz seam-side down. Cook for 2-3 minutes on each side until golden brown. Repeat until all blintzes are cooked.

6. Serve: Dust the cooked blintz with powdered sugar and serve warm, accompanied by fresh berries or fruit preserves. Add a dollop of sour cream or yogurt, if desired.
