Sardinian shepherds carried pane carasau into the hills because it lasted for months without spoiling. When they needed a meal, they had only what they carried and what they could find. Broth from simmered meat or bones. A few tomatoes cooked down. An egg from a nearby farm. Cheese from their own flocks. From these fragments, they created something unexpectedly refined.

Pane frattau is construction, not cooking. Each element is simple on its own. The transformation happens in the assembly and in the eating. The crisp bread softens in broth but keeps enough texture to hold the layers above. The tomato sauce soaks downward. The egg sits on top like a promise. When you break the yolk and it floods the bread beneath, you understand what the shepherds knew: humble ingredients, treated with respect, become more than the sum of their parts.

This is not a dish you can make ahead or keep warm. You assemble, you serve, you eat. Immediately. The bread continues to absorb liquid every second it sits. Five minutes too long and you have mush. The urgency is part of the pleasure.
