Here's the whole recipe, including the levain, above:
SOURDOUGH FOCACCIA WITH ROSEMARY
100 grams active, bubbly sourdough starter
100 grams room temperature tap water
100 grams unbleached bread flour
300 grams room temperature tap water
400 grams unbleached bread flour
9 grams (1 1/2 teaspoons) fine sea salt
2 tablespoons chopped fresh rosemary
6-7 tablespoons olive oil
1/2 teaspoon coarse salt (I used Maldon sea salt)
One 2-inch deep 9-inch round pan
3. Cover the bowl with plastic wrap and let the dough rest for 2 hours; it will increase in volume a little but it won't double.
4. Scrape the rested dough to a floured work surface.
7. Cover with plastic wrap and let the focaccia proof until risen to within about 1/2-inch of the top of the pan, about 2 hours.
8. About half an hour ebfore you intend to bake the focaccia, set racks in the upper and lower thirds of the oven and preheat to 425 degrees.
9. Gently poke the fully proofed focaccia with your fingertips to dimple it and drizzle with 2-3 tablespoons olive oil and the salt:
10. Bake the focaccia on the lower rack for 15 minutes, then move it to the upper rack. Bake until well browned and to an internal temperature of 200 degrees, about 10 to 15 minutes longer (see the first photo above). Unmold to a rack and cool right side up. See that the bottom is also nicely browned:
Omit the rosemary or substitute fresh sage or a tablespoon of dried herbs.
For a thinner focaccia, use a 10-inch round pan; it will bake a little more quickly.
That's it for now. Tuesday I leave for a much-needed vacation in Thailand. I'll be posting from Bangkok after I arrive on Thursday afternoon. Some of you know that Thai cooking is my "other hat." I'll be taking a couple of lessons with renowned teacher Khun Gobgaew Najpinij at her school in Bangkok and visiting nahm, David Thompson's restaurant, to write an article about the sweets made there by his partner Tanongsap Yordwai. I can hardly wait.
