01 - In a mixing bowl, combine flour and salt. Create a well in the center, add eggs, and gradually whisk in half the milk. Continue whisking, then incorporate the remaining milk and melted butter until a smooth batter forms. Allow the mixture to rest for 10 minutes.
02 - Heat a 9-inch non-stick skillet over medium heat and lightly grease with butter or oil. Pour approximately 1/4 cup batter into the skillet, swirl to evenly coat. Cook for 1 to 2 minutes until the underside turns golden, then flip and cook an additional 30 seconds. Stack the cooked crepes on a plate and cover to keep warm. Repeat with remaining batter.
03 - In a small bowl, combine cream cheese, sour cream, dill, chives, lemon juice, and black pepper. Mix thoroughly until the filling is smooth and well blended.
04 - Spread a thin, even layer of herbed cheese filling onto each crepe. Arrange smoked salmon slices over the filling.
05 - Roll each crepe tightly or fold into quarters. Arrange filled crepes on a serving platter.
06 - Garnish with fresh herbs and lemon wedges. Serve immediately while crepes are tender and filling is cool.
