When making a galette, the crust is just as important as the filling. You'll need a visually stunning finish on the folded-up crust edges to match the glossy filling you'll create with butter.
To use egg wash the proper way, just whisk together one whole egg with a teaspoon of water and brush it on the folded dough edges. This will enhance the browning effect and create a gorgeous golden crust with a subtle sheen.
For savory galettes, top the egg-washed crust with chopped fresh herbs for a refreshing taste and crushed nuts or flaky salt for texture.
