Olive oil gives the dough softness, makes it elastic, and as a result the bread has fantastic texture and flavour, and it freezes well. This means that you can bake several ciabattas at time, and put a few of them in the freezer. To preheat ciabatta, you will need to let it come to room temperature and then put it in a preheated to 180°C oven for about 5 minutes. After that, it will be as crispy and delicious as freshly baked. Sometimes I add avocado oil instead of olive oil to add flavour. This gives the ciabattas an avocado flavour.
