Ingredients:
260 gramsall-purpose flour
120 gramswater
75 gramsripe sourdough starter (100% hydration)
30 gramsextra-virgin olive oil, plus more for brushing
5 gramsfine granulated or superfine sugar (not confectioners’)
5 gramsfine sea salt
Sesame seeds, za’atar, herbes de Provence, for topping (optional)
Directions:
Mix the dough (9:00 a.m.)
In the bowl of a stand mixer fitted with the dough hook attachment, mix the flour, water, sourdough starter, 30 grams of the oil, the sugar, and salt on low speed for 1 to 2 minutes, until combined and no dry bits of flour remain. Increase the mixer speed to medium-low and mix, scraping the bowl as needed, for 5 to 6 minutes, until the dough clumps around the dough hook.
Preshape the dough (9:15 a.m.)
Line a sheet pan with parchment paper and use a pastry brush or paper towel to brush on a thin layer of oil. Transfer the dough to the center of the sheet pan and use your hands to form the dough into a 14-by-3-inch rectangle. Use the oiled pastry brush and brush on a very light layer of olive oil to the top and sides of the shaped dough rectangle.
Proof the dough (9:30 a.m. to 12:30 p.m.)
Cover the sheet pan with a reusable airtight cover or greased plastic wrap, and let it rise at warm room temperature (76°F/24°C) for 3 hours, until the dough has puffed slightly and feels airy when poked.
Shape the dough (12:30 p.m.)
Place a rack in the middle of the oven and heat to 375°F (190°C). Line a second half sheet pan with parchment paper.
Uncover the proofed dough rectangle. If using seeds or spices, sprinkle them over the proofed rectangle now.
Using a bench scraper, cut the dough rectangle into about 20 short (½-inch) strips. I like to press directly down with the bench scraper and slightly push the cut piece away to create space.
Using both hands, grab a strip of cut dough by the ends and stretch it out in a single motion to about 12-inches long, which will fit inside the second sheet pan running parallel to the short sides. As you stretch each piece, place it in the pan and lay it very close to, but not touching, the stretched piece before. Repeat with remaining dough pieces.
Bake the grissini (1:00 p.m.)
Bake for 22 to 28 minutes, until the grissini just starts to turn a golden brown color and are crispy.
Remove the pan from the oven and let cool on the pan for 5 minutes. The grissini will keep well for several days after baking stored in a paper bag on the counter to maintain their crunchiness. I find they’re even better the day after baking.
