01 - Whisk together flour and salt in a bowl. Create a well in the center, add eggs, and pour in half the milk. Whisk gently to combine, then add remaining milk and melted butter. Mix until smooth and let rest for 10 minutes.
02 - Heat a 9-inch non-stick skillet over medium heat. Lightly grease with butter or oil. Pour approximately ¼ cup batter into the pan, swirling quickly to coat the bottom evenly. Cook for 1 to 2 minutes until golden underneath, then flip and cook for 30 seconds. Stack finished crepes on a plate and cover to keep warm. Repeat with remaining batter.
03 - Combine cream cheese, sour cream, chopped dill, chopped chives, lemon juice, and black pepper in a small bowl. Mix thoroughly until smooth and creamy consistency is achieved.
04 - Spread a thin, even layer of the herbed cheese filling over each crepe. Arrange slices of smoked salmon evenly over the cheese layer.
05 - Roll each crepe tightly or fold into quarters. Arrange neatly on a serving platter.
06 - Sprinkle additional fresh herbs over the crepes and arrange lemon wedges alongside. Serve immediately while crepes are still slightly warm.
