01 - In a bowl, whisk together flour and salt. Make a well in the center, add eggs, and pour in half the milk. Whisk gently, then add remaining milk and melted butter. Mix until smooth. Let rest 10 minutes.
02 - Heat a non-stick skillet (about 9 inches) over medium heat. Lightly grease with butter or oil. Pour about ¼ cup batter, swirling to coat the pan. Cook 1–2 minutes until golden underneath, flip, and cook 30 seconds. Stack finished crepes on a plate and cover to keep warm. Repeat for all batter.
03 - In a small bowl, combine cream cheese, sour cream, dill, chives, lemon juice, and black pepper. Mix until smooth and creamy.
04 - Spread a thin layer of herbed cheese filling over each crepe. Lay slices of smoked salmon over the filling.
05 - Roll up each crepe or fold into quarters. Arrange on a serving platter.
06 - Garnish with extra herbs and lemon wedges. Serve immediately.
