Sourdough Focaccia - cooking recipe

Ingredients

1 1/3 cups of refreshed sourdough starter
1/4 cup oil (I use olive bit salad is ok)
2 teaspoons sugar
3/4 teaspoon salt
2 cups unbleached all-purpose flour
1 tablespoon oil, for the top

Preparation

Combine the the above ingredients, kneading in flour 1/2 cup at a time.
Let rise till double, punch down, and kneed a little to let the gases out.
Let the dough relax for 10 minutes or so .
Roll the dough into an oval about 9x6 and place on your favourite baking surface.
The dough should be about an inch thick.
Make dents all over the surface of the dough.
Pour on olive oil liberally and spread it all around. It will pool in the dents.
Top with herbs and spices, and possibly parmesan.
My favourite is fresh ground black pepper and coarsely ground salt,.
Let rise until double again, and bake at 450\u00b0F for 15 to 20 minutes,or until brown and sounds hollow when tapped on the bottom.
