Karen loves these at Le Pain Quotidien so I thought I would make them for her.
To make the starter: Combine the starter ingredients, cover, and let rise at cool room temperature overnight, until expanded and bubbly.
Preheat the oven to 350°F.
Place the hazelnuts in an ungreased 9″ x 13″ pan. Bake them for 24 minutes, or until they’re a light golden brown. Set them aside. As they cool, the skins will come off easily.
To make the dough: Combine the starter, flour, salt, water, and yeast, mixing and kneading to make a soft dough.
Knead it for several minutes. The dough will be sticky, but try to avoid adding more flour.
Place the dough in a lightly greased bowl, cover, and let rise for 45 minutes.
Gently deflate the dough, turn it over, and let it rise an additional 45 minutes.
Knead the nuts and raisins into the dough. It might take a while.
Divide the dough into 12 equal pieces.
Working on a floured surface, stretch and roll the pieces 10″ long. Place the flutes 2″ apart on two lightly greased or parchment-lined baking sheets, six to a sheet.
Cover with lightly greased plastic wrap, and let them rise for 2 hours at room temperature.
Preheat the oven to 375°F.
Bake the flutes for 10 minutes.
Gently lay a sheet of aluminum foil over each pan. Bake for an additional 20 to 25 minutes, rotating the pans in the oven (top to bottom, bottom to top) midway through the baking time. The finished flutes will be set and barely beginning to turn golden.
