For the best saffron flavor, steep the saffron threads in a tablespoon of hot milk or alcohol (like rum or vodka) for at least 30 minutes, or even overnight, before adding to the dough. Ensure milk is not too hot when adding yeast, around 105-115°F (40-46°C), to avoid killing it. Brushing with egg wash gives a beautiful golden sheen. You can also add a pinch of cardamom for an extra layer of spice.
