-
1
Remove the biga from the refrigerator 1 hour before you plan to make the bread.
-
2
Cut it into about 10 small pieces with a pastry scraper or serrated knife.
-
3
Cover with a towel or plastic wrap and let sit for 1 hour to take off the chill.
-
4
Stir together the flour, salt, black pepper, and yeast into a 4-quart mixing bowl (or in the bowl of an electric mixer).
-
5
Add the biga pieces, mashed potatoes, oil, rosemary, and 3/4 cup plus 2 tablespoons water.
-
6
Stir with a large spoon (or mix on low speed with the paddle attachment) for 1 minute, or until the ingredients form a ball.
-
7
Add more water, if necessary, or more flour, if the dough is too sticky.
-
8
Sprinkle flour on the counter, transfer the dough to the counter, and begin to knead (or mix on medium speed with the dough hook).
-
9
Knead for approximately 10 minutes (or 6 minutes by machine), adding more flour if needed, until the dough is soft and supple, tacky but not sticky.
-
10
It should pass the windowpane test (page 58) and register 77 to 81F.
-
11
Flatten the dough and spread the roasted garlic over the top.
-
12
Gather the dough into a ball and knead it by hand for 1 minute (you will probably have to dust it with flour first to absorb the moisture from the garlic).
-
13
Lightly oil a large bowl and transfer the dough to the bowl, rolling it around to coat it with oil.
-
14
Cover the bowl with plastic wrap.
-
15
Ferment at room temperature for approximately 2 hours, or until the dough doubles in size.
-
16
Remove the dough from the bowl and divide it into 2 equal pieces for loaves, or 18 equal pieces (about 2 ounces each) for dinner rolls.
-
17
Shape each of the larger pieces into a boule,as shown on page 72, or shape the smaller pieces into rolls, as shown on page 82.
-
18
Line a sheet pan with baking parchment (use 2 pans for rolls) and dust lightly with semolina flour or cornmeal.
-
19
Place the dough on the parchment, separating the pieces so that they will not touch, even after they rise.
-
20
Mist the dough with spray oil and cover loosely with plastic wrap.
-
21
Proof at room temperature for 1 to 2 hours (depending on the size of the pieces), or until the dough doubles in size.
-
22
Preheat the oven to 400F with the oven rack on the middle shelf.
-
23
Remove the plastic from the dough and lightly brush the breads or rolls with olive oil.
-
24
You do not need to score these breads, but you can if you prefer (see page 90).
-
25
Place the pan(s) in the oven.
-
26
Bake the loaves for 20 minutes, then rotate the pan 180 degrees for even baking.
-
27
The loaves will take 35 to 45 minutes total to bake.
-
28
Bake the rolls for 10 minutes, rotate the pans, and then bake for 10 minutes longer.
-
29
The loaves and rolls will be a rich golden brown all around, and the internal temperature should register at least 195F.
-
30
The loaves should make a hollow sound when thumped on the bottom.
-
31
If the loaves or rolls are fully colored but seem too soft, turn off the oven and let them bake for an additional 5 to 10 minutes to firm up.
-
32
Remove the finished loaves or rolls from the oven and cool on a rack for at least 1 hour for loaves and 20 minutes for rolls before serving.
-
33
Enriched, standard dough; indirect method; commercial yeast
-
34
Day 1: 2 1/2 to 4 hours biga
-
35
Day 2: 1 hour to de-chill biga; 12 minutes mixing; 4 hours fermentation, shaping, and proofing; 20 to 45 minutes baking
-
36
You can attractively garnish this bread by embossing a sprig of fresh rosemary in the top of the loaf.
-
37
Mist the dough just after the final shaping with water and lay the sprig flat so that it adheres fully.
-
38
Dont leave any of the needles hanging in the air, as they will burn during the baking stage without the protection of the dough.
