In a medium bowl, whisk together eggs, sourdough starter, maple syrup, vanilla, cinnamon, and salt until smooth and slightly frothy.
Heat a cast-iron skillet over medium heat and melt a little ghee to coat the surface.
Pour a thin layer of the egg mixture into the skillet, tilting the pan so it spreads evenly (like a crepe).
Cook for about 1–2 minutes, then flip gently and cook the other side until golden.
Repeat with remaining batter, adding a touch more ghee as needed.
Serve warm, rolled or folded, with butter and maple syrup on top.
