tips from our bakers
When making yeast bread, let the dough rise to the point the recipe says it should, e.g., "Let the dough rise till it's doubled in bulk." Rising times are only a guide; there are so many variables in yeast baking that it's impossible to say that bread dough will ALWAYS double in bulk in a specific amount of time.
Don't skip the step of brushing the dough with the egg/water wash before sprinkling on the filling. The egg is what keeps the bread from "gapping" around the filling.
If you bake this bread in a 9" x 5" loaf pan, it'll be flatter and not as nicely domed. It will have risen to about even with the rim of the pan when it's ready to go into the oven.
