Adding the finishing touches to a bread is usually done after proofing.
Glazes can affect the finished taste and texture of the crust as well as the appearance.
A glaze is applied either before or after baking, depending on the glaze and the effect desired. Some glazes can be brushed on both before and after baking. This not only will make it difficult to remove the loaf from the pan, but can prevent the loaf from expanding fully in the oven. Use a clean, soft pastry brush to apply the glaze. Glazes are applied after baking to add flavor to the bread and to soften the texture of the crust.
