Dust with flour if mixture is too sticky, or add water (sparingly) if too dry. Cover with plastic sheet or dish towel and set aside to rise for another 2 - 3 hours, until double in bulk. Spread olive on the bottom of your baking pan (11 1/2 inches by 15 1/2 inches).
Place dough in pan and stretch dough into sheet, pressing down firmly with your fingers to make indentations every 1/2 inch or so. Mix 1 tablespoon coarse kosher (coarse) salt with about 3 tablespoons water and 3 tablespoons extra-virgin olive oil.
When salt has partially dissolved, dribble mixture over dough and gently work into indentations with your fingers. Preheat oven to 450 degrees. Allow dough to sit for about 1/2 hour, then bake for 15 to 20 minutes, until focaccia is golden.
Serve hot or at room temperature.
