I baked three loaves of beer bread. Same recipe the only difference was how I treated the dough ball then how I baked it.
When the dough is placed in a hot oven, it puffs up in the first few minutes. This is called oven spring. If the dough skin dries too quickly the rise may be hindered. Two ways to permit the maximum rise are washes and scoring.
Washing with a glaze
A wash is applied to the dough before baking. A wash helps keep the skin of the dough pliable is the early bake. It may also smooth or colour the crust as well as add flavour. Some washes also provide the glue if you want to add seeds to the crust. Once the final proof is complete, the finish of the crust is determined. Glazes affect the look, taste and crunch of the crust. Some are classics such as washing a Challah with egg and topping with sesame seeds. But it is really up to you, the baker, as to how you will finish the loaf. Here is a list of glazes to choose from.
Water – crispy crust
Water may be brushed on or spritzed. Water keeps the dough skin from forming the crust, enabling the dough to expand. It also smooths out the crust, creating a more refined appearance. Apply just before baking.
