Will my bread dough that has already gone through first rise be okay to bake after three days of refrigeration? I was making a loaf of bread in a bread machine on dough setting. This includes the first rise. Removed dough and put into a pan for second rise then bake. My oven died before second rise so I refrigerated the greased and covered dough. It has been three days will it be okay to bake?
From experience... No, it will probably not be 'okay to bake'. It's not going to rise, the yeast will most likely be spent.

Try mixing more dough and incorporate a third of your dough into that as a starter. Then, when that dough is finished mixing, cut a third of it and put it in the fridge for the next time you make bread. Then you've got a heck of a nice starter going.
