1
To make the sponge, in a 3-quart mixing bowl place the water and sprinkle the yeast on the surface.
-
2
Add the flour and stir with a rubber spatula until it forms a heavy paste.
-
3
Cover the bowl with plastic wrap and let the sponge rise at room temperature for about 1 hour, until the sponge has doubled, then refrigerate for at least 8 hours, or overnight.
-
4
For the dough, remove the sponge from the refrigerator and stir in the 1 cup of flour and the salt.
-
5
Knead by hand to form a smooth, elastic, and slightly sticky dough, about 5 minutes.
-
6
Incorporate the remaining flour, a tablespoon at a time, if the dough is too soft.
-
7
To mix the dough in the food processor, place the sponge, 1 cup of flour, and salt in a work bowl fitted with a metal blade.
-
8
Pulse repeatedly until the dough forms a ball (if the dough will not form a ball, add the remaining flour, a tablespoon at a time, and pulse until the ball forms).
-
9
Let the dough rest for 5 minutes, then let the machine run continuously for 20 seconds.
-
10
To mix the dough in a heavy-duty mixer, place the sponge, 1 cup of flour, and salt in the bowl of a mixer fitted with a dough hook.
-
11
Mix on low speed to form a smooth, elastic, and slightly sticky dough, about 5 minutes.
-
12
Incorporate the remaining flour, a tablespoon at a time, if the dough is too soft.
-
13
Scrape the dough into an oiled bowl and turn the dough over so the top is oiled.
-
14
Cover the bowl with plastic wrap and allow the dough to rise at room temperature until the dough has doubled, about 1 hour or so.
-
15
Scrape the dough from the bowl onto a lightly floured work surface and deflate the dough by folding it over on itself 5 or 6 times.
-
16
Return the dough to the oiled bowl, cover again with plastic wrap, and refrigerate for 8 hours or overnight.
-
17
Remove the dough from the refrigerator and deflate the dough as in step 4, above.
-
18
Divide the dough into three equal pieces (about 7 ounces each).
-
19
Cover two pieces loosely with plastic wrap so they dont dry out.
-
20
Working with one piece at a time, shape the dough into a sphere by tucking the bottom under and in toward the center all around.
-
21
Press and stretch the ball of dough into a 12 x 6-inch rectangle.
-
22
Working with the long edge, fold the dough in thirds.
-
23
Pinch to seal the seam.
-
24
Use the side of your hand to press a depression lengthwise down the center of the dough.
-
25
Pinch the sides of the depression together so the dough forms a tight cylinder, then roll the cylinder back and forth under your palms to lengthen it.
-
26
Extend the ends slightly so they form points.
-
27
Arrange the loaves seam side down on the prepared pan.
-
28
Dust the loaves very lightly with flour and cover them with a piece of oiled plastic wrap or a lightly floured towel, then allow to rise until the loaves have doubled in volume, about 1 hour or so.
-
29
About 30 minutes before you intend to bake the loaves, set the racks at the middle and lowest levels of the oven and preheat to 500 degrees.
-
30
Set a pan on the lowest rack.
-
31
You will pour water into it to make steam during the initial part of the baking.
-
32
Open the oven, then averting your face, quickly pour a cup of hot water into the hot pan.
-
33
Close the oven for a minute.
-
34
Use a razor blade or the point of a very sharp knife to make 3 to 4 diagonal slashes across each loaf.
-
35
Avert your face again and immediately place the pan with the slashed loaves in the oven.
-
36
Lower the oven temperature to 450 degrees.
-
37
In 10 minutes, pour another 1/2 cup water into the pan.
-
38
About 20 minutes after the loaves have gone into the oven, remove the water pan and lower the temperature again to 350 degrees.
-
39
Continue baking for 20 to 30 minutes longer, or until the bread is well risen and a dark golden color.
-
40
It should reach an internal temperature of about 210 degrees.
-
41
Remove the loaves from the oven and cool on a rack.
