A simple, quick focaccia made with sourdough discard, olive oil, and fresh rosemary. Baked in a hot cast iron skillet for a shatteringly crisp crust and tender, airy interior.
Ensure baking powder is fresh for proper rise. Do not skip heating the pan, as this creates the crispy crust. If using a glass pan, increase baking time by 5-10 minutes. Variations include adding garlic, parmesan, sundried tomatoes, or jalapeños.
