1 cup buttermilk (or milk)
¾ cup rye (or AP, or white wheat) flour
¼ teaspoon kosher salt
2 tablespoons plus 4 tsp. sugar
¼ cup unsalted butter, melted, plus 8 tsp., room temperature
Lemon wedges (for serving)
Blend eggs, egg yolk, buttermilk, and milk in a blender until smooth. Add rye flour, all-purpose flour, salt, and 2 Tbsp. sugar and blend well. With blender on low, gradually stream in melted butter. Strain batter through a fine-mesh sieve into a large measuring cup or medium bowl.
