Use cold butter for flaky layers. Avoid overmixing the dough to keep scones tender. Room temperature wet ingredients help the dough come together smoothly. Use ripe but firm strawberries to prevent soggy dough. Egg wash is optional but recommended for a golden crust. Cut scones evenly for uniform baking. Store leftovers in an airtight container at room temperature for up to two days or freeze for up to 2 months.
