This Perfect Rustic Sourdough Focaccia with Rosemary and Sea Salt is a simple, forgiving bread made with just four ingredients. It features crispy edges, a tender crumb, and the unmistakable tang of sourdough, perfect for lazy afternoons or as a versatile side.
Use an active, bubbly starter for best results. If your kitchen is cool, bulk fermentation may take 8-10 hours. Be generous with olive oil for crispy edges. Dimple the dough firmly to create pockets for oil and salt. For a gluten-free version, try a 1:1 gluten-free flour blend, but results may vary.
