Rustic-looking and flavorful, with a flour-streaked crusty exterior and extra-chewy interior pockmarked by air bubbles, this classic Italian-style bread is made from just 4 ingredients. Making these ciabatta rolls is a 2-day process. For best success, I strongly recommend reading through the recipe before you get started. Do not be shy with the flour when flouring the work surface and your hands. Use as much as you need to handle the dough. If you have one, use a kitchen scale to measure your ingredients by weight (in grams). With this sticky dough, a bench scraper is basically an extension of your hands. It helps you shape and neatly straighten the dough.
