In a large bowl, combine the flour and salt.
Slowly whisk in the milk until no lumps remain, followed by the eggs.
If too thick, slowly add a little more milk. If too thin, slowly add a little more flour.
Cover the bowl with a towel and allow to rest at room temperature for 30 minutes.
Place a large nonstick skillet or pan over medium low heat. Lightly grease with butter or oil.
Whisk the sparkling water into the batter.
Once thoroughly heated, add 1/3 cup (80 milliliters) batter to the center and immediately tilt the pan in a circle to coat the bottom in a thin layer.
Cook until set on the top and the bottom turns golden, about 2 minutes.
Flip and cook until the other side is golden, 30 seconds to 1 minute. Remove to plate. Rub the pan with more butter or oil and repeat with remaining batter.
When the pancakes are cool enough to handle, tightly roll each up and slice into thin strips about 1/4 inch (6 millimeters) thick.
Divide the strips among four bowls.
Heat the broth, season to taste, and pour over the pancake strips. Garnish each bowl with fresh herbs.
Serve immediately.
