Ciabatta bread is a type of Italian bread that is known for its porous and airy texture, chewy crust, and irregular shape. The bread is made with a high-gluten flour, water, salt, and yeast, and is often shaped into long, flat loaves or rolls with a slightly curved surface. Ciabatta bread is often used for making sandwiches, as well as for serving with soups, salads, and other dishes.
