When bread ages, the starch hardens and seems dry.  To resoften unsliced bread, sprinkle the crust/surface with water and put in a hot oven for a few minutes.  450 degrees F for  2-5 minutes.  Watch it closely.  Warm bread will taste “fresh” again.  To refresh sliced bread, wrap in foil and reheat to soften.  Do not refresh bread in a
microwave.
