Guttiau bread is a traditional Sardinian flatbread that is known for its crisp texture and delicate flavour. It is made from a few simple ingredients, including durum wheat flour, water, yeast, and salt, and is traditionally baked in a wood-fired oven. The dough is rolled out thinly and then baked until it is crisp and golden brown. Once the bread is fully cooked, it is brushed with olive oil and sprinkled with coarse sea salt, which gives it a slightly salty and savoury flavour.
