Divide dough into 8 pieces. Working with one at a time, roll out on a lightly floured work surface as thin as possible (each should be approximately 10″ in diameter). Brush about 2 tsp. chicken fat on dough and top with about ¼ cup scallions; season with salt. Roll dough away from you (like a jelly roll) into a thin cylinder, then, starting at 1 end, wind roll onto itself to create a coil (like a cinnamon roll). Cover with plastic wrap and repeat with remaining dough. Let rest at room temperature 15 minutes.
