Pour the warm water into the bowl of a stand mixer fitted with a dough hook. Add the yeast and let stand for 10 minutes or until foamy. **
1⅓ cup warm water, 2¼ tsp active dry yeast
Add the olive oil, sugar, salt, and half of the flour. Mix on low until a loose dough forms. Add the remaining flour in 1/2 cup increments, waiting for each addition to become fully integrated before adding more. ***
2 tbsp olive oil, 1 tbsp sugar, 1 tbsp salt, 3½ cups all-purpose flour
Once the dough cleans the sides of the bowl and feels only slightly tacky to the touch, transfer it to a floured surface and knead it for 5-7 minutes or until the dough feels smooth and elastic. Form the dough into a ball and transfer it to an oiled bowl. Cover and let rise for an hour and a half or until doubled in size.
Once the dough has risen, preheat the oven to 375°F. Punch the dough down and grease a small baking sheet with a little olive oil. Stretch the dough to fit the baking sheet and create a series of dimples with your fingers on the surface of the dough.
Drizzle the dough with additional olive oil and press the orange slices on top. Repeat with the pieces of feta and sprinkle the dough with sea salt. Transfer the focaccia to the oven and bake for 30 minutes. Turn on the broiler and broil until golden. This should take less than 5 minutes. Don't walk away.
2 oranges, 125g (4.5oz) feta cheese, sea salt
Take the focaccia out of the oven and garnish with parsley and crushed red pepper flakes. Slice and serve.
¼ cup fresh parsley, 1 tbsp crushed red pepper flakes
