We had some fresh rosemary that was reaching the end of its life, so I stumbled upon this 
recipe on Pinterest and decided to give it a go.
yield: 1 9x13 loaf of focaccia bread
 
ingredients
1 package (2.25 tsp) dry yeast
1/3C warm water, about 100 degrees
2.25C tepid water
2 tbs olive oil, plus more for the pan and to paint on top of the bread
3C bread flour
4.5C all-purpose flour
1 tbs sea salt, plus more for sprinkling over the top
2-3 tbs finely chopped 
fresh rosemary
directions
- Stir the yeast into the 1/3 cup of slightly warm-to-the-touch water and let it rest for 10 minutes.
 
- In a stand mixer, pour in 2 1/4 cups of tepid water and 2 tablespoons 
olive oil.
 
- After the yeast has rested for 10 minutes and has begun to 
froth, pour it into the water-oil mixture.
 
- Using paddle attachment, add 2 cups of  bread flour and the tablespoon of salt.
 
- Add the 
rosemary.
 
- Then, cup by cup, add the rest of the flour (both the 
bread flour and all purpose).
 
- As the mixture goes from a batter to a 
thick dough, you'll want to switch from the paddle attachment to dough hook.
 
- Knead the dough using the dough hook on low speed for 8 minutes.
 
- In a large clean bowl, pour in about a tablespoon of oil and put the 
dough on top of it.
 
- Spread the oil all over the dough.
 
- Cover the bowl 
with plastic wrap and set aside to rise (in a relatively warm spot or at
 room temp) for an hour and a half until bread about doubles in size.
 
- Spread a little olive oil in a 9x13 baking dish.
 
- Place the dough in your baking pans, spreading out evenly.
 
- Cover the bread and
 set aside for another 30 minutes.
 
- Dimple the bread with your thumb. Push in to about the end of your 
thumbnail, roughly 1/2-inch.
 
- Cover again and leave it to rise for its 
final rise, about 2 hours.
 
- Preheat oven to 400 degrees.
 
- Once the dough has done its final rise, gently paint the top with olive 
oil – as much as you want.
 
- Sprinkle the sea salt on top from 
about a foot over the bread; this lets the salt spread out better on its
 way down and helps reduce clumps of salt. 
 
- Put the bread in the oven. 
 
- Bake for a total of 20-25 minutes.
 
- When the bread comes out of the oven, turn it out onto a rack within 
3-5 minutes; this way you'll keep the bottom of the bread crispy.
 
- Let 
cool on a rack for at least 10 minutes before eating. 
 
- Enjoy!
