Sourdough's everywhere in Australia now — seems like everyone's got a starter bubbling away on their bench, giving it a name, treating it like a pet. Fair enough too, because good bread is worth the effort. This focaccia uses sourdough starter instead of commercial yeast. It takes time but most of it's just waiting. The dough gets dimpled with your fingers, drizzled with olive oil, topped with rosemary and tomatoes. It bakes up golden and crispy on the edges, soft in the middle. The smell fills your house. Break it apart with your hands, share it around. This is proper bread.
