Baking:

• Drizzle a generous pour of olive oil over the dough
• Lightly wet your hands and using your fingers, gently press down into the dough creating dimples. This is what gives focaccia its signature look. It is important to do this step gently. You want to create dimples in the dough but avoid knocking all of the air out of it.
  
• Add a sprinkle of flaky sea salt and chopped rosemary and place it in the 450 degree oven.
• Bake for 20 - 30 minutes until golden and crunchy on the outside, but soft in the middle
