Remove from refrigerator.
Focaccia should be more than doubled by this time.
Oil a large baking sheet (13 x 9.5) with olive oil. Place dough on baking sheet. Do not stretch out yet.
Cover for one hour. Set the oven 500 degrees on bake mode.
After one hour, stretch dough out to fit the pan.
Pour water and olive oil mixture over the focaccia (about 1/4 cup).
Use finger tips to make the focaccia holes all over.
Sprinkle with flaked sea salt.
Reduce heat to 480 degrees F. Bake for 20 minutes or until golden brown. After ten minutes turn around in oven for more even baking.
Focaccia makes great sandwiches. Cool. Cut into squares and use bread knife to cut crosswise.
