Can I refrigerate bread dough after the first rise and bake it later?
Yes, you can refrigerate bread dough, and in fact you will probably find that it will give you better, tastier results, because the yeast has more time to do its work. Any bread baker worth his salt (flour?) will tell you that a slow, cold rise is better than a fast, warm one.

You should refrigerate the dough immediately after mixing, not after a rise. Depending on the amount of yeast in your recipe, this can be for a few hours or even overnight. Allow the dough to warm up a little before baking.
