1
IN A LARGE MEASURING CUP, combine the yeast, sugar, and 1/2 cup of the water and stir to dissolve.
-
2
Allow to stand for about 10 minutes, or until the yeast mixture forms a frothy head.
-
3
(If no head forms, the yeast is bad.
-
4
Discard the mixture and start again with fresh yeast.)
-
5
Stir in the remaining 1/2 cup water and the olive oil.
-
6
IN THE BOWL OF A FOOD PROCESSOR fitted with the metal blade, combine the all-purpose flour, whole wheat flour, polenta, rosemary, orange zest, and salt and process in several short bursts to combine.
-
7
With the motor running, add the yeast mixture through the feed tube in a steady stream, taking about 10 seconds to pour it in.
-
8
Continue to process for 10 seconds more, by which time the dough should have formed a ball on the stem.
-
9
If the dough is too wet and forms a ball right away, remove the cover and sprinkle 2 tablespoons of all-purpose flour over the dough.
-
10
Or if it is too dry and has not formed a ball on the stem within 15 seconds, sprinkle over 1 to 2 tablespoons more water.
-
11
Process in 5-second bursts 3 more times, then turn the dough out onto a lightly floured board and knead for 1 minute.
-
12
The dough should be slightly soft but not sticky.
-
13
BEGIN STRETCHING, pushing, and pulling the dough with your fingertips and the heel of your hand into an 8 x 12-inch rectangle.
-
14
This will take a while as the dough will be very tight at first.
-
15
Be patient: Within about 5 minutes it will soften up and acquiesce.
-
16
Transfer the dough to a generously oiled baking sheet and brush the top of the dough with more oil.
-
17
Cover with a tea towel and allow to rise in a warm, draft-free place for about 45 minutes, or until puffy.
-
18
PREHEAT THE OVEN to 400F.
-
19
TRANSFER THE DOUGH to an unfloured cutting board and cut it crosswise into 4 equal sections.
-
20
Cut them crosswise into 8 little strips and roll each one under the palms of your hands into a thin rope about 12 inches long.
-
21
Transfer to oiled baking sheets.
-
22
Do this in batches if necessary, keeping the unrolled strips covered with the towel and rolling them out just before baking.
-
23
Brush with beaten egg and sprinkle with fennel seeds and coarse salt to taste.
-
24
BAKE FOR 15 MINUTES, or until slightly golden.
-
25
Serve warm with a little dish of your best extra virgin olive oil or cool on racks.
-
26
(The breadsticks will keep in an airtight container for up to 2, weeks.
-
27
To serve them after they have been stored for a few days, reheat on a dry baking sheet, uncovered, at 350F for 20 minutes.)
