01 - In a mixing bowl, whisk together flour and salt. Create a well in the center, crack in the eggs, and pour in half the milk. Whisk gently to combine, then add remaining milk and melted butter. Continue mixing until smooth and free of lumps. Let the batter rest for 10 minutes to allow gluten to relax.
02 - Heat a 9-inch non-stick skillet over medium heat. Lightly grease with butter or cooking oil. Pour approximately ¼ cup batter into the pan, immediately tilting and swirling to coat the bottom evenly. Cook for 1 to 2 minutes until the edges lift and the bottom is golden brown. Flip and cook for 30 seconds on the second side. Transfer finished crepes to a plate, covering to keep warm. Repeat with remaining batter.
03 - In a small bowl, combine softened cream cheese, sour cream, chopped fresh dill, chopped fresh chives, lemon juice, and freshly ground black pepper. Mix thoroughly until completely smooth and creamy. Taste and adjust seasoning if needed.
04 - Lay each cooked crepe flat on a clean surface. Spread a thin, even layer of the herbed cheese mixture over the entire surface. Arrange slices of smoked salmon over the cheese filling, leaving a small border around the edges.
05 - Roll each crepe tightly from one end to the other, or fold into quarters by folding in half then half again. Place assembled crepes on a serving platter, seam-side down if rolled.
06 - Sprinkle additional fresh chives or dill over the top for color and freshness. Arrange lemon wedges alongside the crepes. Serve immediately while crepes are still slightly warm and the filling is creamy.
