Optional Demerara edge: Before baking, chill the formed dough until firm, very lightly moisten only the outside edge with water or melted butter, then press 2–3 tablespoons coarse Demerara sugar onto the edge. Keep the top mostly bare. This adds a sparkling caramel/toffee crunch while preserving the tender center. For the first batch, the plain version is recommended. High-quality butter matters substantially because butter is the dominant flavor.
