How can you get scones to turn brown on top in a gas oven?

To achieve a golden-brown top on scones in a gas oven, ensure you preheat the oven adequately, typically around 400°F (200°C). Brush the tops of the scones with an egg wash, made from beaten egg mixed with a splash of milk or water, before baking. This not only enhances browning but also gives a nice sheen. Additionally, placing the scones on the middle rack ensures even heat distribution for optimal browning.
