I usually take out what I want and seal it back up and either just keep in in the refrigerator. Or, I separate it into sandwich baggies, 2 at a time or one ciabatta at a time and then place all the sandwich baggies into a gallon sized freezer bag and freeze it. That way, I can take out just what I need for the day. I especially love the ciabatta toasted! I forgot to bag up my bread this week; left it on the kitchen counter. Two days later, when I went to make a sandwich I was shocked and appalled to reach into the bag and find my hand covered with black, hairy mold! YUK! Never had that happen before! Of course, we've been having hot, humid weather this week so I'm guessing that's why it happened. Needless to say, I won't be leaving it out on the counter anymore!
